I know people hate homogenisation of classes but I think this should be the default. With this change I can keep casting Concitation while summoning Seraph and tell her to cast Consolation, while I can cast Medica III without delaying Assize or combo them together for big aoe heal.

Stat wise they're already the same with their 1.5s counterpart in SGE and AST. The goal is gameplay fluidity.
