+ % damage mod question for Bard/War/Paladin

[Bumkus]

Do you guys have a way to boost you damage during burns?

I usually don't cast my Group Bestial Alignment during burns because most melee have a way to boost there damage higher that GBA provides.

Here is GBA detail
2: Cast: Group Bestial Alignment Form
4: Increase Chance to Resist Spell by 20%
5: Increase Hit Damage by 30%

I can cast it during burns if it helps you guys out.
