Im sorry but that is not entirely true. It is not for the sake of teambounding experiments or "fun" that pretty much most top orvr guilds have felt forced to run PvE to gear out.
and we are not talking about minor mainstat improvements here.
Its fair that you want pve gear to be attractive to add content, I get it. But atleast make invader somewhat decent. because it is a direct downgrade on all stat-fronts for some (70%?) classes.
