Here's the thing. To people who play this game like it's their job, the PvP can be learned and yes, I suppose you can argue that it's all upto player skill. Which is how it should be.
But I am a returning player, and I am joined by a bunch of entirely new players. And 'getting good' in this game is nearly impossible. Why? Because you can't see what the hell is going on and you can die in 3 seconds flat. When I played this game back before HoT and shortly after, the time to kill was average. You had some time to react, Some opportunity to counter and if you lost, you had an idea - however vague - of what happened. You didn't see the shatter, you used your stab too soon, your boons got converted. So you knew what to look out for and slowly you could improve.
Now? F'ck off with that, now if you're new, you die in an explosion of particles in several seconds, most likely chain CC'd even with a break free and you get sent back to spawn with no clue about what in the hell you could have done better or what even killed you. I used to duel a lot, and each duel lasted a fair bit. From each one, I learned something. When to attack eles, when to dodge and what to dodge. Now in duels I get chain CC'd and deleted in the blink of an eye and my recap tells me almost nothing. Amidst an ocean or particle effects, I see nothing. Boom you took 12k+ damage in 0.5 seconds. Better luck next time.
Time to kill is way too low for people to learn, is my point. We have all the right to complain about this PvP.
