Next expansion, please make PLD optimal MT and WAR optimal OT

[Mithron]

V5s: WAR MT, PLD OT. This is the norm, pug convention. No tank swaps.
V6s: Same, no tank swaps.
V7s: Same, no tank swaps, except if OT gets virus. Then OT tanks for a minimal amount of time before swapping back.

Susano ex: PLD actually makes a good MT here for Hallowed Ground on first Stormsplitter, but WAR obviously pulls first for optimal DPS and aggro gain (even if it's not needed at all). Has good tank swaps.
Lakshmi ex: PLD best OT, no tank swaps needed.
Shinryu ex: PLD best OT, only tanks for a minimal amount of time between invuln Ahk Mourns and Terra Slashes.
Byakko ex: PLD best OT, tank swaps minimal amount of time.

This is the problem. I shouldn't have to build a static to go out of the way to play sub optimally with PLD MT'ng.
