I think you can definitely see the party setup.
Let's say you can anticipate or react.
Example of reaction:
- my tank is dead, I cast raise
- my healer have 0 mp, I cast ballad
Example of anticipation:
- my tank is gonna get hit by death sentance soon, I'm gonna fill his HP before
- my mages will have to spam medica soon, I'll start regen MP
- my melees are going to use a lot of TP soon, I'm gonna fill their TP and regen it a bit with paeon
Example of super-pro-player-anticipation:
- "guys, I'm gonna sing paeon during the packs on T4 so you can go crazy with AoE killing stuff faster" ^.~)b
