Spines overall will probably get more kills due to range. If however you find a way to keep your opponent in melee range MA will easily out damage spines.
TP Foe and weapons mastery can help get many players into range and keep them there but still range will probably win out IMHO.
And in any case, if u dont like spines, EM will always do more dmg than MA
Currently, i am playing a MA/SR stalker, but after seeing a video of the spines powers in action, im wanting to know if i should stick with MA or switch to spines.
i mean, i can knock enemies out of the sky easily with one of my MA moves or air superiority, but with spine's impale, i could do that from a distance....
so which power pool beats the other? im still sticking with super reflexes however.
