way i see it, those guys on the hill are smarter at GVing than the average joe
therefore are considered "pickers" (first time i heard that for a GV?) 
Those,,, er us,,, guys on the hill remember the old hills with a forest thick as anything ever, and the lack of any good bombs to penetrate the brush,, I have been shooting of the tops of those hills for 5 years now, and no young punk is gonna get me to stop anytime soon!
have fun trying tho
even if I lose a hundred points a day,, it is still fun,, heck i used to land 25 kills a night in a jeep,,, what the heck are you gonna teach me by bombing the hills? and do you really think you know something about tank town that none of the rest of us do? it is just a fun place to fight,, that is all,,, most of the good spots have been corrupted over the years,, but there are a few left i haven't told anyone about!
