If you really think that the 9x19 needs a buff, you're living on a different planet. It's super accurate, and Tachanka really is viable. His support as an operator is very good. If you think he is bad, I suggest roaming with him, and putting his turret + shield in very important angles. Best thing is to buff his turret.
I was talking about his LMG, how did you even manage to figure that I was talking about his SMG.
And no, he isn't viable. He's hardly ever played, he has no playability on ESL or ranked. Casual doesn't count because it's CASUAL. He's the least played operator, before and after the buffs.
He's support yes, but a god awful one at that, sitting in one spot with a shield that requires a single magazine from any gun (Except Glaz's) to break.Oh yeah, did I mention the shield doesn't cover his legs at all? So you're forgeted if someone's got your foot at an angle. Team coordination doesn't matter when you're the first one dead because you're a sitting duck and any kind of explosive or distraction get you away from your turret.
He's a stuff operator, has a stuff gadget, and is useless other than being a recruit with two reinforcements.
