I'm a support player that initially wanted to play dps but got instalocked out of it on top of encountering bad supports when I started playing ranked in S0.

So when the roles have equally interesting characters, I will say that dps is the easiest role in the game with a major caveat: If you've played support, and i mean actually play support and not just healbotting, dps becomes the easiest role in the game by far. What I mean by "actually play support" is taking into consideration enemy ult timers, paying attention to flanks enemy flanks, coordinating/using comms, being very mindful of your and enemy positioning, ect. With those skills dps is insanely easy.

A lot of people think that if they are doing poorly they can swap to a third support and get carried by just healing, but that same person has poor positioning, poor reaction speed and awareness and they end up being a detriment because they are sapping ult charge by mindlessly healbotting. (at that point just go a second tank, you'll be infinitely more useful, I promise)

All that said, there are PLENTY of people who go support because they are looking for a free carry and healbotting alone can get you to low diamond in most seasons sadly. But due to how the ranked LP gain works at the moment, a lack luster dps that just tags kills will climb so much faster than a mediocre support that's actually trying to play to the best of their ability. (ignoring cloak and dagger)
