There's no length where it's too long, as long as you're not burning at like 60-70% mana. If you stay at 85%+ mana constantly never dropping stacks, that's great! Just watch your evocation timer for the next burn and don't start it too early.Is there a length that is too long for the burn to last? What do I do if I get constant missle procs, and am high mana 40+ seconds into the burn? Do I just end the burn without evo?
Because evocation mana regen scales with arcane charges.If evo removes all stacks, why don't we cast Barrage right before we evo? Is there a reason some of the top logs on Gruul cast barrage in the middle of their burn phase?
The second part, I don't know why they would do that. Movement perhaps.
Yes, 30 seconds is really long though, I wouldn't until boss will die within like ~20 seconds. (I made that mistake sometimes, and being below 50% mana for the last 15 seconds of the fight really hurts your DPS)Also, I assume when the boss gets low health, or ~30 secs from enrage, we add an extra burn even with no evo up?
