Harbor Viper was mainly cool because Harbor's fun to watch, honestly. But then people got sick of Skye, so she got nerfed to the ground. We thought we'd see less Viper as a result but it was actually Harbor's pickrate that tanked; Viper went up to like 80%. Then we realized how insufferable watching Viper nonstop on every map is, so she got nerfed to the ground as well. Now we're watching Omen on every map but I don't think anyone cares because people just like Omen so darn much. And then we also got Clove who's getting more play than not only Harbor but also Brimstone and Astra, even though she literally has one piece of util that ever gets used, which is literally just a worse Omen smoke.
That was quite the little rant I just went on but my point is: Viper on every map is boring, Omen on every map is boring, and we really need to balance the controllers so that they all see equalish amounts of play (except Clove I hate Clove she sucks)
