What do YOU do at 55?

I prefer to play my alts. Once the class story is over it's hard for me to motivate to play a character - the planet quest that is Makeb did nothing to alleviate this. I try to keep them in my playing rotation to slowly gear them up, do some crafting, work on achievements, finish up companion affection, work on rep., save money for Treek.

Why are there only 4 hard mode 55 flashpoints? Thats never made much sense to me. The 50s are too easy, and the 55s are too repetitive since there are so few of them.

I run around in circles on the fleet in boredom.

Ops and finishing up old stuff like companion affection, crafting, FP story quests, other than that, I make a new character. Doing new class stories is the primary reason why I keep playing.

which is great but i myself have nearly got my trooper to lvl 55 which is the only one i have that isn't, ive got all the class story's and makeb for them they are well geared and ive done ops in story and dont really care about HM versions.

I have always said that theme park mmos need some sandbox elements to really keep people interested, a hybrid of both sandbox and theme park would do wonders for mmos like this.

Pretty much the same here with the difference that I only started my 5th class so far so still a bit left until I run out of new characters to make. Guess I will just take longer breaks when I'm done and come back for story expansions. The more grindy stuff or "time sinks" (like Seeker Droid/Macrobinoculars) I only do on my Rep and Imp mains but that won't be enough to keep me playing as often as class stories can.

Are you seriously making a post about this? Tell me.. What replayability is there in any other MMO? What replayability is there in a game like WoW, rift, Gw2, aion, tera, or any older games such as EQ2? At the end of the day, dailies, dungeon grind, pvp grind, and raids. Thats it. If the game doesn't seem interesting to you, then why play? The reason the game doesn't have a whole lot of content, is because its not exactly an old game. Content is being updated. Content people like? Occasionally. But they already said that they were working on adding more story content and such. What do you what them to do? Keep adding story content each week, until 3 months later the games definate end? Jesus...

Somewhat offtopic as SWTOR hasn't implemented it: User generated content is a way to add a lot of content. However it is difficult to balance and people try to exploit it to provide easy money/ drops / XP farm for people and then it gets nerfed to the ground by the devs. And if it provides poor rewards, few people play it. (See Neverwinter).

On Topic: Some fun minigames would be a good addition to SWTOR, like Pazaak and Swoop Racing. Maybe an arena with random PVE fights with cool looking species not just mostly (demi)humans for some solo/small group content. Space content that is different than a rail-shooter (very lame to me) would be cool too.
I still have plenty to do, level the rest of classes to 55, get some gear , play around with different companions, level at least one other force "caster" (most fun class to me), etc.

I kill wookiees.... Never fails to entertain me and there are just to many of them to ever get done with it.
I feel bad, if I have to spend a day without having killed at least 2 of them and I think it is a serious flaw in game mechanic, that you cannot bio-harvest their remains.

It would be cool to run FP's with just your companions so you don't get bored of waiting forever, gearing them up is fun too.
