Blizzard lead designer Geoff Goodman revealed his team is working to change up Overwatch's Torbjorn in a big way. The plan is to make Torbjorn more offensive, by removing Molten Core and giving him the ability to toss his turrets out.

In an interview with VG247, Goodman said, "With Torbjorn, the issues we're trying to solve are that he's a little overly defensive focused. We need him to be more viable on offense in a non-payload situation. It doesn't mean he needs to be equal on offense, but we need him at least to not be a troll pick." Goodman further explained that Torbjorn's abilities "snowball" by starting out weak and becoming incredibly powerful by the end of a match. Goodman doesn't want players who use Torbjorn to bounce back and forth between being useless and being useful. Torbjorn should be able to assist his team at any point in the match.
