This skill has been overlooked for a while but it most definitely needs to be toned down. It does way too much on a short cooldown. The only reason why it's been left like this for so long is because very few people play it. But for those who play in relatively high ranks on NA will know that one particular Scrapper player has centered his build around this skill for a long time, to great success. Please devs, look into this. I am not the only one, there are numerous other posts if you do a simple search.
