I'd like a week of 1 and a half years or so worth of nerfs reversed. So we can all experience the game how it was just after slots where added.
Or just a couple of days, to put things in perspective.
I think that would be awesome as well. The slots were a good system to put in place, and right around that time (or shortly after) is when I think everything was pretty well balanced. Sure some things were stronger than they should have been, or weaker than they should have been, but nothing was so outrageous that a little bit of adaptation and teamwork couldn't over come it.
We've had so many nerfs, and then something else becomes imbalanced, so we nerf more shit, and then that breaks something else, so obviously that means we need to nerf something else.
I don't really like all the nerfs, and wish people would suck it up, and try to change the way they're playing (to overcome the obstacle) rather than running head first into it and complaining on the forums when the obstacle doesn't move for them.
