We don't want Arcane to sit at max stacks all the time. As a player who is focused on maximizing DPS, you're going to want to maximize stacks, but it's not always going to be easy to do - that's the challenge of mastering the spec. The reason we lowered the stack size is we felt that having to build up to 6 made dropping stacks feel too punitive.
- Also for Arcane, Scorch deals 40% less damage for Arcane only, but its damage and mana are now increased by Arcane Charges. We agreed that previous iterations were too punitive for Fire and Frost. For Arcane, using Scorch as part of the base rotation won't be as powerful as it is today on live (which we feel violates the stack management I mentioned above), but it will increase with stacks.
- We are still iterating on Blazing Speed.
