First off, I just want to state that this is coming from a perspective of someone who plays as primarily melee characters that do not utilize cloak.Therefore, all arguments for “get gud” are null and void for my take on the “cloak” mechanic. These are my observations of the mechanic, from the perspective of someone that actually take advantage of the way it is now.
My argument is that the mechanic feels useless as an escape tool in the current state that it is in. Provided that I’m close enough to the person that goes cloak, I can still clearly see their silhouette, and keep stabbing away at them. It gets even worse if they have any sort of debuff on them that applies any sort of visual feedback (burning, slowed, and so on). They light up like Christmas trees, and they might as well not be cloaked at all.
My suggestion is, at the very least, remove visual feedback indicators for debuffs when an enemy goes cloak, if not remove the debuff status completely. If removing the debuff isn’t feasible for balance, then at least removing the visual effect would help. In all honesty, I feel like there shouldn’t even be a silhouette, but some may find that OP.
