How many skills is too many?

[Makeda]

I think any action bar over 8-9 is bloated. At the most 16-18 with using the shift key to get to the other half.

But lets look at it from a what is needed point of view:

Tank:
1. Basic threat attack
2. Basic AOE threat attack
3. Ranged pull
4. Taunt
5. Interrupt
6. Damage mitigation
7. Avoidance mitigation
8. Minor Self heal
9. Gap closer

DPS:
1. Basic single target attack
2. DoT attack
3. AOE attack
4. CC attack
5. Interrupt skill
7. mitigation skill (avoidance or damage)
8. gap closer / widener (closer for melee, widener for ranged)
9. Minor self heal

Healer:
1. Single target spike heal
2. AoE heal
3. Heal over time - single
4. Heal over time - AoE
6. Gap widener
7. Enmity reduction
8. Basic attack
9. Resurrect skill

Everything else is bloat.
