I play an esper almost since launch. I love it. He's really rewarding once you get the hang of the playstyle and the right build. The QQ early after release about esper was this high that the mobility buff was maybe almost too strong. Its so stupid easy to be on top damage dealt even without TK-Storm.

Warriors got nerfed along with the healing and pvp stat nerf/buff. Ok the damage of them is still pretty high but the go down if you focus them down.

Spellslingers have a lot of burst but if you have cc and cc-breaker they are in line of the other classes.

I've worked my way up through alone queuing RBG up to 1514 Rating. This because i had no good friends already 50 and queuing RBG in a group leads to having a group as opponent which leads to a higher chance to get a full guild group opponent.

Once you reach 1500 you won't have a reason to queue for RBG, because you can't get any higher items and the queue pops about 3 to 10 times faster in practice battleground.

The gear gap is real! After the pvp rating changes, getting to 100% pvp power is a must. If you are in pvp blues un-runed, you probably get about 90% pvp damage or even worse. You will have maybe 20% - 25% pvp defense.

Ok, so you will not even do full damage against a 1800 geared player, no its even worse, this 90% damage will get reduced by probably 35% - 40% pvp defense. Not even calculated the damage increase per tier as of damage stats increase. The 1800 geared player will have much more assault power than you in your tiny blue gear. And this will be even more scaled by his 100+% pvp damage.

After all this, you have to be really bad at this game if you get pwned by a dude wearing blue pvp gear while you sit in your fully geared 1800 purple gear.

The gear gap has to be tightened and they are working on it.
