Hi,
first of all, I do like the pvp stuff, finally we got some juicy content in this matter, have been waiting for so long!
Finally a balanced (not fully yet) pvp experience with everyone having same conditions (gear etc). In the vanilla game, pvp was a matter of the insanity of your pvp gear. If you had none, you automatically lost against players wearing it.
But: What the hell is wrong with balancing there? I see classes that deal like 5-10k per hit, others 500k+, some even 1kk+. That should take a while for balancing everything properly I guess. It feels like casting classes are much more powerful than instants, but wl/ch seems to be entirely broken, such as d/wl or k/m.
The most annoying thing is, that there is no buff cancel at the entrance. You can even farm/use patt/matt sigils outside and they don't expire inside. Also, the damage and sustain difference between unbuffed, selfbuffed and fully buffed is insane. While unbuffed players hit with like 1k per second, a fullbuffed player literally oneshots unbuffed/selfbuffed players. Depending on your class, you can also oneshot fullbuffed players while being fully buffed yourself. Feels like wild west duels: First pulling first shooting first winning...
You should also disable invisible Potion in Battleground, which is another annoying thing. First seconds of fight no damage is dealt, since all players are running around invisible xD
Long story short, I have high hopes in the update, hopefully you can keep up your good work (the rewards are just awesome!) and make pvp something great! (90% through balancing ofc) 
Request: Please add more Battleground modes, like "1v1 (no buffs mode)", "1v1 (selfbuffs mode)" and so on. Would me much appreciated, since you literally can only win atm if you buff yourself into heaven. 
Otherwise please let quitting opponents count as loosing and in 1v1 the other "win" the game instead of just giving no rewards at all, which feels bad if you buff up for nothing.
