Sniper + Tinker

Why this works

Trying to build a team around both Sniper and Tinker creates an immediate drafting problem. Both heroes are incredibly farm-dependent and want to occupy a core position, which puts a massive strain on your team's economy from the very beginning. They also share the same fundamental need: a strong, durable frontline that can create space and peel for them. When you pick both, you're left with three other heroes who must fill the roles of initiator, tank, and sacrificial support, making your strategy predictable. You end up with two glass cannons and not enough shields.

This fragility gets exposed hard in the mid-game. The enemy team knows you have little initiation and will simply run at you, forcing bad fights. Tinker wants to split the map and apply pressure with Rearm, while Sniper wants to group with his team to siege. These game plans often conflict, leaving Sniper without his globally mobile partner when a fight breaks out. The opponent can focus on whichever hero is more out of position, knowing there's little the other can do to help. Your team ends up playing reactive, separated, and hoping for a pick-off instead of executing a real strategy.
