Torbjorn players have it easy for them because their turrets do a lot of their DPS. Turrets still take knowledge in where to build them throughout the maps and some basic skill for using his Rivet Gun.
Rivet Gun:
Torbjorn's weapon does require some precision in learning how to aim properly as he shoots out projectiles that has a travel time to its destination, although it's not terribly difficult to get used to.
Build Turret:
A two year old can build a turret, but knowing where to build the turrets can take a little bit of knowledge. Once the turret is up it works for you and you only need to keep an eye on its hitpoints to repair it after it takes damage.
Armor Pack:
Torbjorn can collect scrap from dead heroes and then throw out Armor Packs from it. Collecting scrap is probably the most difficult aspect of it and overall it is a very easy ability to do.
ULTIMATE Molten Core:
Torbjorn's ultimate turns his turret to level 3 (as long as its currently level 2 at the time), and he also gets an increased amount of armor to go along with it, which is a relatively safe ultimate to use and is easy at the same time. Knowing when to activate it can take a little knowledge.
