Sorc: Nice damage, absorb shield with low cd, force run, stun, interrupt, knockback, roots, snare, instant immobilize skill and nice heal in dps spec.
Sniper: Big damage, absorb shield with cure effect + some absorb thing when he enter cover, covers (immune to interrupt, to force leap, and 20 sec immune for everything CC every minute), snare, root, knockback, close range stun, aoe immobilize
Now look at mercenary: Big damage (Not bigger then sniper, srsly pretty same) most crap defense shield, range stun, knockback with low cd and immobilize with unreal cast time, and that all what have mercenary..
Why you still whine about tracer missiles? Mercenary have NOTHING for runaway from enemy, or reach enemy, he cant interrupt healers, merc can only stay and damage.
I don't say mercenaries is bad class, i have top damage every match (i think only because snipers have very low population) and i like play it, BUT STOP WHINE, MERCENARY NOT NEED NERF.
P.S. only what i want to merc, its some escape ability, like force run (we have jetpack's and don't really use it, lol) or jump to friend targets..
P.S. sorry for my English.
