My build is dagger and shield(the one allows you to use holy skills) bruiser. So most of my damage is coming from the explosions of mark of impurity and whirlwind axe + earthquake jump. This build is focusing on gathering crowds and killing all together in a single boom. The problem is when like %60-70++ of my screen is full of enemy which is pretty normal in an ARPG game, skill effects stop working. I use my jump ability, it does jump but there is no damage or earthquake effect or mark of impurity explosions just disappear without doing any dmg or spreading the mark, Im also pretty sure when this happens i dont do an poison or bleed dmg which is so bad cuz i have the only deal material dmg passive. And also there are server lags, when you are killing the last 3-4 mobs of huge crowds(like 1 full screen of monsters), it lags for 10 secs some dmg input and output things happen and your die or live.
