I feel like I need a good break down of weapons going from pve to pvp

I have weapons all over the place some simulare stats some diff but in PvP they are a metric mile of. How well does multi attack work does it not show that power in PvP. My wizard is like 40 power but puts out crazy DPS… Is multi attack good with whirl wind i feel like It should but from description I feel it doesn’t affect it can we make this topic as good as that huge one about luck I just found

multi atk was like weapon dmg but it is better to use multi atk for other skill for example bullets 1 bullet + multi atk = 3
