Finds a couple champs you like in each play style (Attack, Defend, Rush) and master each of them. I would recommend having a go to for supporting as well as it wins games.
I would say the addition of single player is one of the biggest differences but other then that they are very similar in most aspects. I would say that Battleborn is more of a MOBA then Overwatch which I would say is a a team shooter and is the spritual successor to team fortress.
I've bought 5 5$ packs and gotten at least 1 gold if not 2 in every set. My drops rates are extremely high compared to those I play with. They hate my guts.
Very nice thread.
I would be careful doing anything will glitches or the such. Blizzard has already started banning people for modding and who knows where their policy stops as far as any exploits.
