Sam:

Make hasso and Seigan last 30-60 mins, it's pointlessly annoying for them to be 5 minutes. Needless annoying busy work.

Geo:

Reduce the recast timer on entrust to 5-6 minutes, with so much content being mobile now it would make geo more useful (considering it has little melee capability as cor and bard do)

Drg:

Decrease call wyvern to 5 minutes, 20 mins if far too long.

Puppetmaster:

Increase Maneuver duration to 5 minutes full time, there is no reason for it to be 1 minute and slowly build to 5.

Ninja:

Make Yonin and Innin 30-60 mins duration.

Blue:

Lower recast of Diffusion to 5-6 mins.
