If they only win trade for an hour or two, then if they cannot win trade, that is potentially an hour or two extra they can spend in proper PvP matches, so again, a positive. The only people really likely to out right stop are those who
need an easy way, and I really doubt those are the ones doing PvP properly when they're not win trading, anyway. The players who play properly and win trade are not the ones likely to stop outright if win trading goes away.
I agree.
Like I've said, win trading is really just a symptom.
