I think the main issue right now is that a lot of people don't know how to kill the Templar legit. Atheon is a difficult boss, but the community has adapted to killing him legit. Once people get used to killing the Templar legit, it won't be an issue any more. The same complaints were around when the Atheon fight was patched. You don't really see people say it's too hard any more. Just that the glitches can cause wipes.
