I know all too well that it takes them off radar. The point I'm making is that any competent player can still easily kill them. Players that rely on invisibility are typically awful at stealth and flanking; they don't try to use the map to their advantage. They're easy to spot because, while it makes them invisible in radar, it doesn't completely make them invisible in the environment. They have a distorted static effect around the character model when they're invisible. Players that use it from a distance can't really do much with it. Is they try to use a sniper or linear fusion rifle while invisible, the glint from them will give away their location. They'd have to be really good at quick-scoping to make it work.
