This then leads to the whole "BiS" argument. BiS comes down to iLvl and which secondary stats are better for that job: Crit/Determination/SkillSpeed, etc.

But it takes a LOT of any of those stats to see a measurable difference in your tanking/healing/damaging ability. The only secondary stat with any worth is accuracy. Once you hit that, it doesn't really matter what the other stats are. Have you ever tried to stack a lot of crit hit or determination? The gains are very very small. The difference between a full mythology geared job and a "BiS" job are extremely minor.

Take that, and consider what will happen when they remove the myth cap next patch. It really removes any need to do CT (past your first job to 50) or earlier turns of coil. Just grind myths in Pharos/Haukke/etc and anyone can be i90 in a short time.
