So you're upset that a melee had too much going for it. More than anything titans and warlocks have. Smoke took away radar, blinded, weakned, disrupted, and slowed had area denial, two versions of wall hacks, reduced player movement, jump height, and suppressed abilities. Could stick to guardians and wall surfaces. Has lingering effects when you leave the smoke, also had radar manipulation. You could also make your self and others invis stacked for additional benefits with exotics and could bypass its entire cooldown dodging at a wall. This -blam!- has been broken for like over 5 years now. It needed it.
