Get 50 as both classes and then come talk it out. Marauders own face at 50.... My bh merc, I switched to heal spec just cause well its hard to dps verse well made teams that know what to do. Bh dont have much escape just a aoe knockback, single target stun, and a single target mini knockback if your spec for it. Oh and unload snares. Marauders are very useful at 50, they have leap/root, force choke, heal debuff, vanish (escape), snare, and the reduce all dmg taken (escape).
