I honestly see no point in Ghillie Suits I don't have a problem seeing people using these suits even when they are hiding with it. I think people should be allowed to wear the Ghillie Suit with out a sniper because the fact they aren't hard to spot even on Prison Break. I don't think anyone could hide from my friend even with a Ghillie Suit cause he looks for pixel displacement so it would be impossible to hide from him. Back on topic though I don't see any problem with them and I don't even have one unlocked yet. I think it would be hilarious if someone used a Ghillie Suit while using nothing but explosives though.
I think the sniper suit should only be for snipers. They should have to sacrifice a perk for overkill if they want to have a regular gun. I know the game isn't realistic, but I don't see Seals, Rangers, Delta breaching buildings in ghillie suits.... I get it that it's "cool" and this is a game, but character models should be suited and used for what they represent.
