If you want to keep having high DPS against bosses, stick to devourer bottom. However, if you only want high numbers in stats =/= more DPS, go Lion's Roar or whatever you want.
Maro set for damage? Definitely no. It does give you 5k ish damage, but thats nothing since you lose 15% damage against bosses, tons of crit and crit damage. It'll only make you tankier.
