I do agree that summoner is much more difficult to play well than in heavensward. Kinda the opposite of what they said they were trying to achieve with class changes in stormblood.

Definitely need to roll back some things and make major changes imo.

Couple things off the top of my head:
1. Allow us to select our target for devotion buff and make it an ogcd instead of a pet ability.
2. Allow aetherflow stacks to overlap with dreadwyrm stacks again.
3. Make wyrmwave into an auto attack for bahamut.
4. Allow rouse to be useable on bahamut.
5. Buff bane potency. No one is using it anymore because its usually a dps loss compared to painflare.
