it'S not necessarly pay to win, but they are implementing more and more stuff to make you wanna spend money.
also the RNG is very bad when putting stones in your gear or when using enhancement stone to up it.
thats the most annoying part of the game, like /bash head in wall.
so the easy p2w stuff they sell to make enhancing/stoning your gear easier or more accessible becomes tempting.
but even so the bad luck of randomness can strike!!
so... it is becoming p2w, at least in pvp, where enhancing your gear really counts toward dmg reduction and dmg increase
