Yeah, got my Vanguard to 41 last night and still loving the game. The main thing I wish they'd improve is the LFG tool, I don't want an LFD tool like in WoW, but they should at least have the option to only show people who are LFG & galaxy wide, preferably with some filters. Right now you can flag yourself as LFG & add a comment, but on /who it still lists everyone on your planet (limited to 100), just adds a symbol next to who's LFG. So if you want to group it's mainly spam in General chat.
Even PvP isn't so bad, everyone gets bolstered to 50 (though they intend to make a seperate warzone for lvl 50 now) and the only advantage higher level brings is more abilities. There's 3 warzones: one is where a ball is dropped in the middle and you have to get it to the opponents base which ends up being very chaotic, another is to fight for control over 3 cannons untill you get destroy the enemies' ship and in the last one you have to slice (hack) a terminal, but you need to blast through 2 doors first and attackers and defenders get switched around so you play once as attacker, once as defender. There is some open world PvP on Ilum as well, but I haven't experienced it yet. Part of the fun now is of course that everyone still figuring out what to do. Though I guess you'll get premade teams eventually (not sure you can join with more than 1 group though, kinda hope not).
So far I've liked all the stories I've played through (though I've only done the starter planet with most, only my smuggler is higher than lvl 11).
