Cast bars still required less assets than this system.
But yes, they're much more likely to give us an entirely new system in 6.0 than revert back to what it was before.
I love how you are basically saying "AST only has a chance to get in when being picked against WHM. SCH will always have a spot so its AST vs. WHM."
Instead of, you know, saying that you want AST to compete with both of them and that all of them should be equal? You know, so, WHM/SCH, WHM/AST and SCH/AST are all usable and all about the same when it comes to optimal runs.
But you seem to have already resigned to the "its SCH/WHm or SCH/AST".
