So i have a level 41 carnage marauder and i have almost maxed comms and around 700 ranked warzone coms. I was wondering if i should convert all my ranked warzone comms to normal comms when i hit 50, or if I should spend them on EWH. I heard that EWH was bad, and if it's true should i keep stacking warzone comms to convert later, buy level 40 pvp armour, or buy medpacks and adrenaline.
