I would quit playing.
Having a large amount of abilities with complex or interesting interactions is a huge part of why I find WoW more fun than many more recent MMOs.
Think about how same-y healers would feel if they had 8 or 10 buttons.
- A single target damaging ability.
- An AOE damaging ability.
- A single target heal
- An AOE heal
- A cleanse
- A stun
- An interrupt
- A movement ability
- A heal over time
- A defensive
That’s boring. That’s lame. That sucks. That’s neutering classes and their identity and what makes them unique.
