I have been level 30 for 3 days, my gear is ok for only having crafted one thing so far.
I just wish farming hard mode missions was a bit harder because its like a hot knife through butter and you can come away with 0 or at best probably 3 purple items, and I know those don't mean much but they break down and sell better.
The DZ is fun to farm if you have a group but as well all know the rogue system is broken and there is no pvp to spice it up there for I much more enjoy doing mission runs I wish there was a middle ground between Hard (ridiculously easy to out gear with just 1 day of being level 30) and Challenging (ridiculously high gear check that will take some time to grind out) Challenge mode tactics are just cheese stun and LoSing into chaining CDs, it looks more fun to do them once you are really geared cause then you don't need these tactics.
Going forward I think they will need to develop some sort of in fight mechanics and it would be nice to see missions with multiple bosses.
Over all I am enjoying the game but the grind at the end is kind of meh right now, I am all for grinding out some min/max stats its just there is no good way to do that solo and the friends I was playing with are playing a lot less then I have since launch =S
I look forward to the patches and DLC content, and I really think some squad v squad pvp games would be very fun in this game with some normalized pvp stat kits.
