I would love to see the following changes come to AST soon

Lightspeed Give a +10% healing potency bonus with instacast but keep the -25% potency when used with damaging spells
Ewer and Spire To give a 30 potency Refresh and Regain effect respectively, even buffed these wouldn't be incredibly gamebreaking considering the RNG involved.
Draw Would love to see the duration of buffs increased to 30sec
Expanded Royal Road Instead of -50% potency I would like it changed to -50% duration, make using it worth it because right now the best we have is +5% attack for 15sec
Collective Unconscious Be floor targetable similar to Sacred Soil and Asylum
Shuffle 45 sec cooldown

I really think the enhanced Ewer would go a long way with helping ASTwith MP issues as well
