Consoltation would be a good change maybe, but the rest of your changes are bad imo.
Using cooldowns appropriately is part of being good at your job, don't need to make it simpler.

Repose is required in the role quests, so even if it's small it serves a purpose.

Emergency tactics is something that has to be manual use due to how it functions. It would be useless if you couldn't do it on demand.

And finally Ruin II being lesser potency than broil but able to be used on the move is an important part of caster DPS balance.
