i dont understand these people... did you actually play a merc? its horrible, powertech is better in assault spec, better then anything merc can bring. arsenal is to easily shutdown, even a recruit gear sentinel can annihalte you not so hard, and assault is simply not reliable.
Arsenal is too easily shutdown because people are not reacting appropriately when they get attacked. All they want to do is spam TM. That's all it is TM TM TM, Unload, Railshot, TM TM TM, rinse repeat.
Yeah as if someone is gonna let you go and spam that from the back row. Same people who used to press 1 button for wins are now crying for a buff.
