Take a look at PoE (1 and 2). Top tiers build players are able to run T17 maps in 30sec and uber boss by staying afk… some average players can’t even kill those bosses, others try hard on them.
Games don’t have to be balanced according to top builds… in fact, evrythink have to be balanced… nerfing some empowered enchant, boost others… It’s easy to deal 1k/more damage wihout OP build…
