Tank LBs reduce a ton of damage, best used when there's incoming AOE LBs. My burst damage turns into a mere mosquito bite against tanks.

Healer LBs are also great in dealing with caster LBs.

Caster LBs are kinda okay. Offensive LBs are deadly when stacked, no matter the form.

I agree that ranged LBs are strange in the sense that they're like a mix between melee and caster LBs. Ironically I find the best use for it is when the enemy's retreating, forcing them to run to the side and delay them for just a split second for my team to catch up. I'll be lucky to hit even more than 1 enemy with it.
