Anyways, it's pretty easy to fix the severity of some of these issues (Moonkin / Ret related) as long as a couple of adjustments are applied such as..
- 2 pieces Balance: When Entangling Roots is dispelled or broken by damage, you gain 1 charge of Starsurge. --> 25% chance
- 4 pieces Balance: When you cast Starsurge, you become immune to Silence and Interrupt effects for 4 sec. -->10% chance
- 2 pieces Retribution: When you cast Avenging Wrath, the duration of all incoming crowd control effects on yourself is reduced by 50% for 15 sec. --> 50% --> 25%
Set bonuses shouldn't redesign the way a class plays although there's a clear discrepancy between some class bonuses and others.
