One thing, everyone is whining about get hoed, picked, rammed, etc, but everyone is doing it.
Nope, not everyone is whining about those things.
The only people that whine about those things are the ones who haven't figured out how to avoid having those things done to them. Those tactics aren't all that difficult to beat, or to potentially even capitalize on.
SA and good ACM defeats the first two.
The third one is seldom the fault of the guy who hit you (do some research on this- I'd go so far as to say that if you get rammed, 99% of the time you should have simply gotten out of the way; for your opponent to ram you effectively, on purpose, he has to MISS you on his screen).
Taking the path you've voiced (fighting the HO, pick, and ram by returning the favor) is going to lead to a lot of frustration for you. Far better (IMO) to just improve
your own skills, and begin slaughtering the guys who'd like to use those tactics against you. Asking for folks to change their ways to suit your desires is a long, frustrating, selfish, and ineffective means to make the game better for yourself.
I'd also like to point out that HOing, picking, and ramming are valid, important, and even desirable tactics to have available and present in the game. They keep things interesting, and keep the game far more "honest" than it would be without them.
