AST doesn’t need a buff right now people just need to optimise the fights better and get some more gear and AST will pass WHM like it generally does due to gear scaling, SCH the other buff healer just generally doesn’t rely on gear scaling as much because chain is a good buff regardless of how badly the party performs

I agree lightspeed because locked to the div window makes its 90 second CD pointless but I think 60 seconds and 2 charges is a bit too strong considering SCH also has no lossless movement, just decoupling the forced connection between the two would be better by not forcing so many weaves would probably fix the problem better
