4) Torbjorn
Torbjorn is the quintessential builder for Overwatch, as his turret can dispense some serious damage down range. While it’s not uncommon to see a Torbjorn on defense, multiples of this character are becoming more and more prevalent. He is a very powerful defender class, as the sheer amount of damage both him and his turret combined can do is truly something to be respected. However, what pushes this guy a little over the edge is that his turret can practically come out as soon as the other one is destroyed. Yes, his turret has an eight-second cooldown, but it can be fully set up in under four.
What this leads to is Torbjorn effectively always being able to have his turret up, so as soon as one goes down he can begin rebuilding it. There is no cost to actually upgrading it to tier 2, so if your turret is destroyed in an attempted push you can have it fully operational again before the engagement is probably over. Now, we don’t want to make Torbjorn not viable in Overwatch but there should be a change in the way his cooldown works in regards to placing a turret. Instead of a cooldown activating as soon as you place the turret, it should begin once said turret is destroyed.
Also, there is an argument to be made about how long it should take for his turret to become fully active and opening fire, but something like this would need a lot more testing to get it balanced just right. Torbjorn players should have to be a little more thoughtful for their turret placements, but that is not the case currently since there is really no penalty to it being destroyed at all.
