On the Battle.net forums Overwatch's Jeff Kaplan discussed heroes and "The Future of Hero Balance", answering and addressing some concerns about the game and the heroes in place.
One particular concern he was keen to address was regarding the heroes that are perceived as "troll picks", saying: "It's never our intention to have a hero be perceived as a "troll pick", but that will inevitably happen sometimes. Let's say that we all agreed that all of the heroes were perfectly balanced (just pretend with me), even if we touched nothing, eventually the balance would shift over time due to evolving playstyles, strategies and meta-trends. A lot of us like pro sports and tend to think of those games (soccer, football, hockey, basketball) as "timeless". But if you follow those games closely, the leagues have had to make minor tweaks to the games to keep them fun and balanced over time. It's a weird analogy, but it is very similar to hero balance in a game like Overwatch. In those pro sports, players and coaches evolved their ways of thinking about the game that required the game itself to change at times."
"We will absolutely do our best to make sure all of our heroes [are] viable. With so many heroes, I do believe the playerbase will (at times) decide that certain heroes are out of fashion and therefore deem them as "troll picks". Sometimes this will be very valid. And sometimes it will be perception."
"Both Torb and Symmetra are being looked at right now. We want to try to improve them in ways that makes them more fun to play, more enjoyable to have on your team and try to make sure they are not infuriating to play against."
"We wrestle with the issue that players get very upset at us when they perceive "the meta is stale" and certain heroes are not viable. Yet it's also very disruptive to the playerbase for us to make changes. It's a bit of a Catch-22 but we do our best to responsibly look at all heroes all the time and make sure nothing is terribly unbalanced or worse, un-fun."
What do you think of "troll picks"? Are they a big issue in Overwatch for you?
