WHM has a ton of issues to address but I don't think merging CureI and II should be one of those fixes. The shorter cast time and low MP cost has its niche uses as it is too, but at any rate it still has a fair bit of room with one XHB+WXHB set, unlike AST and SCH.

BeneficII should replace BeneficI since MP isn't a problem at all with AST and their cast times are the same, Draw should turn into Play, and Minor Arcana into Crown Play. I guess they should then move Draw charges to be on the job's UI then, and have Minor Arcana also do the same or activate automatically after 60s. Perhaps they could also get rid of Lightspeed by replacing the spell speed boost on Astrodyne with its cast time reduction.

Then for SCH, they should merge Fey Blessing with Indomitability since the former no longer even uses the Faerie Gauge, and remove Dissipation since it's even less worth using now that Energy Drain doesn't recover MP anymore, then probably just add a trait that adds a 4th Aetherflow charge to make up for that. I may be in the minority but I'm not a fan of losing Emergency Tactics or Physick since I use Emergency Tactics fairly often for when there's a need for extra healing and shields are already applied, and I use Physick every now and then to do minor heals between pulls or boss downtime, or when not even Emergency Tactics is enough and I'm out of aetherflow charges.

Then I said this before but I still think they should merge Summon Seraph with Aetherpact and have her use whatever Faerie gauge you have to focus healing on her target outside using Whispering Dawn/Fey Illumination/Consolation. Consolation's charge time and effect makes no sense with the current Summon Seraph's recast time and being able to have her out more often should help with that.
