I would discuss how different Paladins and OverWatch are, and how brutally misinformed you'd have to be to still think they're ripoffs of each other rather than simply being games in the same genre, but I believe I already argued that point against you in the Paladins topic, and I would be getting off-topic to do so. Instead, I'll ignore that fairly ignorant first comment, and instead address the idea of giving more options.
I agree. More options aren't a bad thing, and heroes in OverWatch are very varied, meaning new characters always add variety. However, I am simply disappointed with the fact that Blizzard seems to be neglecting the other categories, and is instead focusing on the category that needs the least in terms of variety. The existing offense characters are interesting and unique. There's plenty of variety, and its the largest category. Defense characters, as a whole, are picked far less often than offense characters (even on defense, where you'd expect them to be picked). Many are considered unviable, and the category needs some help. The support category is in a similar situation, notably with Symmetra. Instead of giving more variety to the categories that don't have enough, they created another character for the category that doesn't need help, and is arguably the least important category to a good team composition. It makes Blizzard look like they're more interested in drawing in new players than they are about maintaining the game in its current state.
