Please make Cover have longer range.

You are protecting someone from most damage and effects, it's got to have a weakness somewhere. It's ok as it is really.

I can't tell you how many times I've gone to cover the healer and they are halfway across the room, where they should be mind you, and cover not going off at all.

The range of cover is perfectly fine as it is, and 9 times out of 10, you never really NEED to cover a healer, mostly you will use it on a certain tank busters, just to ease CD management, or to optimize a mechanic such as o11s for example, where you have BRD/MCH take the tether and then cover them so they don't die to the AoE following due to health penalty.
In regards healers positioning, halfway across the arena, inside the hitbox of the boss or somewhere in between, is all fight dependent not a where they should be. The correct positioning is where they can effectively heal and dps, or where a mechanic requires them to stand.

This is a problem with the healer and not a problem with Cover. If a healer is getting hit by something that isn't a mechanic specifically designed to hit healers, the healer should be running to the tank and not away. And if the healer is getting hit by something that is specifically designed and intended to hit healers, Cover is a luxury and not a necessity.
