If the post author(s), in general, would be a god using that respective agent that he's asking to be nerfed, then he wouldn't even dream about such questions.
Sova doesn't need a nerf nor a buff. He's perfect as he is (btw, you can destroy instantly the reckon bolt - but again, skill diff :( ). But if he would be nerfed, as you're here asking for it. Then, it would be completely useless and never used again.
Someone here said that there's 15 agents in the game and Sova's picked almost on any map but Split. Let's be honest here, he's picked because of usefulness, not because he is the best agent. And even if Sova would be completely erased from the game, you would complain about the next/ previous agent.
Yes, some minor/ major changes can make the game and agents to look more okayish... but even if RIOT tends/ try to make the agents to be equal... the sad truth is that they never will be on the same standing.
You can take poker card game as an example... if each and every card would bring/ add the same value and outcome of a game; then would it be fun or people would be still playing it?
