Well, there's two ways of "hiding".
One is the obvious dude, who just stands there. And watches.
The other is you occasionally throw in an attack, you fight. It's just rarely.Yyou stay on the outside of action, and you move a lot, people don't go and fight you as much. Simply not fighting doesn't mean you just stand there. What I do, is I keep on the outside, and hit the flying players.
And when someone comes at me, I can already see the fact they are going to attack me. I am better at 1 vs 1s,, so I wait for this to happen, and send them back. If you get a good enough first impression, they get scared and stay away.
Or you can pick on a weaker person so you don't get specially targeted.
It isn't a dumb idea, but how you chose to go out with the whole thing could be. Some people jst stand there...
