SWTOR has generally been bad at providing this because most content requires attention, whether because there is some sort of story going on or because it's of a difficulty level that requires your full focus (e.g. raiding or PvP). Command XP didn't feel like a good addition at first because it made the mistake of wanting to be the only road to gear in town and on top of that it was painfully slow to get anywhere with it initially. With all the changes and buffs it's received since then, it's in a much better place though, and when Bioware announced that we were going to get a week of double Command XP this week (when I had already taken time off work no less), my ears certainly perked up.
Why would I even grind CXP though? My main's already at rank 300 and in full 248 gear. Well, as I said above, sometimes I actually enjoy a bit of grinding - and with Command ranks advancing at twice the usual rate, I figured that it might actually feel rewarding to work on some alts. Not just for the gear - I read somewhere that dataminers have discovered that achievements for getting all eight classes to Command rank 300 might be coming up at some point. As silly as that sounds, for some reason this is the kind of achievement that really tickles my fancy, and I figured I might as well get a head-start this week.
My third character to hit Command rank 300
On Tuesday I was doing a round of Iokath dailies on my Guardian (before the event had even started) and quickly found myself feeling somewhat confused when after completing only two missions or so, I had already gained two Command levels. It was at this point that I noticed some guildies talking about how most dailies were bugged and giving way more XP than usual - fifteen times more than usual in fact! One of them joked about me being an exploiter now, which didn't really worry me as big part of actual exploiting is doing something that isn't part of normal gameplay... but it certainly felt odd, especially when the double rewards event started soon afterwards and those crazy numbers became even higher. Fortunately CS soon confirmed that nobody had to worry about "exploiting" this bug, and Musco's and Keith's official responses on the forums were examples of unusually good PR management for SWTOR: Basically they confirmed that it was a bug, but they could see why people enjoyed it and didn't consider it game-breaking, so they told people that they should enjoy it while it lasts. Keith even took feedback and noted that dailies were probably due for a CXP boost, even if it shouldn't be quite this much.
So I actually did three daily areas on Tuesday, which is a lot for me as someone who's not a lover of dailies. I had no particular urge to just grind on one character like crazy, but instead saw it as an opportunity to give some love to alts that I usually don't play that much anymore. I was reminded that the alignment-resetting bug in Section X still exists when my Guardian was suddenly demoted from Light V to neutral - good thing she wasn't wearing anything with an alignment requirement. In-between I also queued for a couple of GSF matches, since that was the bonus activity for the day, and got what I think is my highest ever kill count in a match!
(This was on an alt with completely un-upgraded ships by the way, and I still think of myself as a very mediocre if not below average GSF player - but I always do a lot better myself if the rest of my team is strong than if I'm surrounded by people just as bad or even worse than me.)
On Wednesday the featured activity of the day were flashpoints, so I figured I would do some more dailies while waiting for pops, but my Imperial healer alts always got hardmode groups so quickly that they never had time to go anywhere. I actually ran six master mode flashpoints in a row that afternoon - I wouldn't have rated flashpoints as a grindy activity previously since they do require a certain minimum amount of attention, but in actuality it was less than I thought, especially in places like the Black Talon. None of my pugs were awful either, though I was a little sad inside when people insisted on running past the bonus boss in BT even though we were on the right step of the chain and he was right there. Some people just seem to be allergic to doing bonuses in the same way that I'm allergic to skipping them. I was somewhat compensated by tanks who later pushed for the bonus in both Boarding Party and Cademimu, which is somewhat rare from my experience.
In the evening I also queued up on my Marauder, who did get to do some more dailies while waiting in the dps queue. The Czerka Core Meltdown I got into had one of the most heart-breaking pug moments I've ever seen, as after two wipes on the Vrblther (WTB some vowels please; I can't believe I spelled that right) the tank told our Sorc healer that he should probably leave and work on his gear some more and/or get more healing practice before trying hardmodes again. "If that's what you want," the healer said and exited the area - he looked so dejected! It was true though that his gear was pretty poor (not sure if bolster still helps if you're level 70) and he did silly things like spam Force Storm on the adds while people were dying all around him, but I still felt bad for him... I was also surprised because he had managed to successfully heal us through the Duneclaw, and I always considered that one much harder to heal. After he had quit, the tank whipped out his Vette to heal and on the next attempt nobody's health even did as much as dip. Companions, man.
Of course today any plans to continue grinding were foiled by a broken patch that was so bad that Bioware had to take the servers offline again immediately after its drop and haven't been able to bring them back up again at the time of writing this. The current ETA doesn't have them coming back before the end of the evening for us Europeans either, but they've said that they'll consider extending the event to make up for the lost time. Who'd have thought that a day would come where I'd be eager to spend some more time grinding dailies in this game...
