Actually, 90% of my PvPing is BS based, 9% duels, 1% TWs.
But when people get to choose between having a char that is good for both BS and TWs, and a char that is only good for BS, people choose the char that is good for both.
150-170 chars are awesome for both BS and TWs.
200 chars will only be good for BS.
The only thing this change proves is that FC ppl don't PvP.
