Honestly, just add some damage around. Give healers something to heal, it's not hard. Unavoidable damage that isnt a lot but can add up if ignored. Give me something to cleanse. Not hard. Get rid of vulnerability if you have to, theres nothing to heal if people are either full hp or dead from missing 2 mechanics. Let us cleanse vulnerability. Something.
Just lazy and safe uncreative development. Theyre too scared of expecting someone who has reached level 90 to actually know how to do anything at all whatsoever.
This is a video game. If they cant press buttons in an order then let them lose.
No one cares about savage. Make it less about researching for a test and more like i dunno, playing a video game and people might play it.
Balance for the majority of content people play which is guess what, normie content. Raids are a waste of time to develop.
Dont make battle content for the lowest common denominator of plot watchers who will never like it. Then youre just making easy boring stuff that no one likes. Raider trash even say who even cares about dungeons anyway.
