Not really. It just makes you better at dealing with that particular brand of bullshit. If you wanna talk about how doing something would make people better, go point fingers at the people who play the stupid characters to begin with.
Also,
Jy0 , not an IGAU player myself, but from everything I've seen from people who aren't idiots, DS indeed did not need to be nerfed. Those who said he did simply didn't know what they're talking about.
Things I believe should be nerfed/fixed actually DO need to be nerfed/fixed, and they're all the obvious things like Kabal, Kenshi, etc. Things that clearly outperform almost everything else in the game for(usually) significantly less effort than anything else.
