Okay, unless you are a very good player you cannot camp mid from the start. You'd have to, at some point restock on gear and food. Granted, you could get a friend to bring gear to mid for you, but a player who is good enough to control mid from the start is not going to play like this.
And about the supposed bow spamming etc from mid. Speaking as someone who is a very good bow spammer, someone who used to bow spam and nothing more, and now someone who rarely buys bows anymore, if you get shot off, it's your own fault. Keep an eye about you and only go when the way is clear.
Final point, if a god PvPer (or, granted, hacker) is camping mid then get your entire team to rush him - it is a team game after all!
