People using free account to troll in WvW is out of hand, it needs to be handle by not letting free account plying in WvW.
the only reason anyone would go to WvW with free account is to troll / spy tactivator pulling , I do not see any other reason anyone would go to WvW with a low level trial account.
it is also damaging to Anet's income when player dont buy gem from the gem store to transfer.
please stop allowing Free Account into WvW. You will have cut down griefing in WvW by a whole lot.
