ZA unfair for alliance on PvP realms

Currently in the PvP PTR, alliance is having a very hard time getting to the instance because of the zone being in horde territory. This is not because of distance but because horde doesn't have to be flagged unless they choose to be, while alliance are forced to be flagged at all times.

This is very unfair for alliance players. I'll give an example:

Five alliance are at the meeting stone along with two horde. These two horde are unflagged and there is no way they would be stupid enough to attack the alliance with fewer numbers. Yet Alliance can do nothing. These two horde soon summon in 8 more horde. Now that they have the upper hand, they kill the five alliance.

What about the fact that horde will always be able to get the first move off? What is alliance supposed to do if they see two unflagged mages casting frostbolts at your healer?

How is this fair?

The whole point of friendly territory was never intended to keep level 70 horde raid groups safe. It's only purpose is to protect lowbies. Blizzard really needs to change this.
