Just gonna toss this out there in regards to the proposed 80% statistic.

WHM is the most played healer in basically all content. If 80% of WHMs healed so little as to let people die all the time, or shoved the full burden of healing onto their cohealers in full party scenarios, wouldn't this be a prevalent enough issue that it would be widely regarded as fact by now?

Like, this would mean the community reaction to seeing a WHM would be "oh no, they almost assuredly aren't going to heal me, I am going to die" which, if we look back at 3.0 AST (which had a different source problem but the end result of not healing enough was the same) would mean WHMs would be getting kicked regularly just for simply being WHMs.

I mean heck, if there was a single job that the presence of signaled death that frequently for whatever reason I would probably be kicking them myself.

So why is it with this ridiculous statistic (and let's be clear even a far lower percentage than 80 would still be laughable but this guy decided to stick to 80 so here we are) even being debated at all?

There is currently zero evidence for the claims the OP has made, far more people countering his points than agreeing with him and ample evidence for anyone who cares to look up actual damage and healing statistics for this game to literally know that this is a bunch of bull.
