This is kinda bad. This can be used basically only to destroy dispensers, or delay a sentry little bit more. The outlining has basically no use if you know wheres the other teleporter. just 1 more hit doesn't really change anything. Damage penalty on sentries and teleporters is AWFUL. Id rather delay or destroy the teleport rather than tracking where it is. I must say this had potential, but overall, this would be worse than stock.
