Most classes have a very specific role. If you are not playing one of that specif classes you are useless. For example a KE should straight out be replaced with a ES. The raid is so ridicules, that characteristics of very specific skills and passives are used. The raid needs to be nerfed to a point were everyone can enjoy it. Not just a very low subset of the palyerbase.
I was already mad because of the incredibly high item level you need in order to play in Vanymir’s dungeons, and this is worsening the situation even further.
Hope they do something to make it playable by anyone.
