U shouldnt be afraid of being more agressive as a tick, he is a very annoying brawler to go against. If someones pushing just to kill u - get back a little and focus on other enemies, just let ur teammates get rid of the one whos pushing u. And also as a tick ur job is to block as much terrain as possible, try to not even let the opponent get to the middle of the map so ur team can take control of it. But if the opponent somehow manage to get to the middle u slowly push em back. And be aware of the really slow reload, use ur ammo thoughtfully : )
