What i think of the new pvp, and balance issue

The new pvp have good idea and less good idea.
The consolided combo don't bug me too much, its not hard to do 1,1,1,1 thats true, but its not hard to do 1,2,3,4 also, everyone can count 1,2,3,4 i think, it's can be boring to press the same button, but it save space on hotbar also, so its not the worst idea i think, i was not missing a combo before because i was doing 1,3,2,4... it change nothing, exept i have to use the same button now.
But why reducing so much the toolkit, and why 12 button when even gamepad player can afford to 16 buttons to be able to play with a single bar.
It feel to much reduced to the maximum.

Balance issue i din't try all the jobs, so i can only tell about what i try

Tank:
Dark Knight and Palladin seem well rounded, Dark Knight seem better to me, he can be a pain, And War is pretty bad now, Palladin and Dark have nice toolkit and war nothing, exept a push back and homlang, stun and silence is better than homlang anyway.
War do more damage with 4 fell cleave? yes but release the inner beast is a 2 minutes cool down you can't do it a lot, it don't save the war i think.
Dark Knight was the bad tank before, now it's the war time.

Healer : I played only sch but what its what i fell about healing :
Frontline is a mess without aoe.
But i think its balanced more for 4vs4 than frontline, it fell easier to heal in 4vs4 because you cast fast, but when you get zerg by tank and both dps, its harder to survive now, also you loose attune, it fell like nothing can save you from this.
Broil on sch is too much OP when a kill happen and there less pressure to healing.

Dps : din't try enough dps yet. summoner is good but i din't try other ranged yet
Sorry for my bad english.

I am so used to 1->2->3->4 that I put the same skill on the first 4 hotbar slots.

I believe it was simplified to try & make PVP more accessible for all players. Many players get overwhelmed with the expanding amount of job actions & combos that they panic during PVP & hit there combos improperly. We can argue that (if you aren't ready for PVP, you shouldn't be playing it) but SE wanted PVP to be played by more players. I believe the changes are extremely useful, the only thing is, you'll have to readjust to your new PVP specific action bar setup. As a healer, I don't have combo buttons, however, it's much more enjoyable & simply to worry about 8 - 10 actions rather than 20+.
