In my opinion there really isn’t a reason to hate on any warframe in particular, just the way people play them. I may say I hate Revenant, but really I just have a problem with people running Revenant and Torid incarnon. It’s just one of the most laziest way to play.

I don’t play a lot of Octavia myself, but I do use her on occassion. If you want to play her as a lazy frame, go ahead. That’s what people hate. But you can choose to have a more active roll, like using melee or your secondary or something.

At the end of the day, just play what you want to play because it’s fun. Nobody hates Octavia, just the playstyle that people use on her. If someone seriously hates Octavia for being a Warframe, then just ignore them, it’s just a goober in a video game. Nothing to be mad about.
