Alt choosing

[MasterRoy]

I'm rather new in this game (been playing since mid October,even thought my account is way older).

My current main is a Gunslinger,and later I created a Blade Dancer too. Since I like this game so much,i just funded myself three more character slots,which i used to create a Force Master and a Warlock,all classes that are good in PvE (judging on faction/clan chats). Now I've an empty slot,tried to fill it with a Summoner,but it isn't just my type.

 

So i ask you all: what class should i choose now?

I'm mostly into PvE and i don't think i will start PvP too soon (because i'm still inexperienced and i would have a really bad time).

I thought about a Kung Fu Master,because i saw he is tanky enough,but how about DPS? Is he sluggish at damage but gets better with grinding or not?
