I'm in favour of BG commands, while they're not particularly blizz-like it adds so much to the PvP environment on a private server (and unless Kronos gets blizz-like population, which no private server has ever to my knowledge achieved) it is quite simply required for a truly active pvp environment both at low levels and end-game.
The reason for this is, without BG commands the majority of the server's population will only touch BGs when they have nothing better to do and they will further be discouraged from doing this, since the only people regularly doing BGs will be the r14 farmers, who will be doing it with premades.
The only problem with BG commands is however that BG farmers can farm gold while farming honor, which leads to an un-blizzlike economy.
I'd suggest adding BG commands that port you back to the location you were at when you entered BGs, however add them with a tax, when you enter a battleground that you have signed up to with BG commands it costs money.
