Guys, it has no similarity to LOL or Smite or DOTA. Those are MOBAs where you have lanes and creeps and have to destroy an Ancient/Base, towers etc. The game that is comparable to these MOBAs is Battleborn.
Like mentioned earlier in the thread, Overwatch is more similar to TF2 and other multiplayer shooter games. Two of the modes are directly same as TF2: Payload and KoTH. The other two are hybrids. Only thing different from TF2 is that hero roster is more expanded and more well defined. Heroes have specific skills and their roles/skills cannot be changed by equipping specific items like in TF2.
