I really cannot comprehend how people don't understand the simple factor of player skill. People see statistics and immediately take it as gospel, as well as failing to look at each phase specifically
on top of all the other factors I've listed, let alone how much you lose if someone is playing a job they're not able to optimise so well because they're less familiar with it regardless of its party buffs. "BUT BRD/DNC IS JUST BETTTURURURURUR"... please. If someone is more comfortable and therefore more reliable mechanically and in terms of consistent damage output on MCH, then you let them play MCH. The same goes for any job/role when deciding on your comp. I'm not talking about world racing or speedkills. I'm talking about prog for any group.
Stop being a sheep and understand that comfort and consistency matters. For the record, we killed P4S Day 3 with a double phys-ranged comp
before gear became a major factor. Is it as tight as the last phase of an ultimate? No. Is it still winnable? Yes, so who cares. Does this justify the position MCH is in? No, and I've complained extensively before as seen here as one of many that have been constructively moaning about it for quite some time -
https://forum.square-enix.com/ffxiv/...=1#post5890630 and I don't agree with how MCH is right now. However, writing it off as objectively not viable is short-sighted.
Dungeon gear that's +5 ilvl will be 6.3 by the way. Always 2 major patches after.
