Well we did out first dredgion against our own faction today, and it sucked. Our team won and stopped the other team which included legion members from getting AP. This game has always been faction vs faction. Stopping your own faction from progressing as quickly really sucks and it felt really bad. I always enjoyed the fact that these PVP instances meant you could deal a blow against the enemy faction, this felt as if I was calling out my own side on the enemies LFG to stop them from doing a daily quest or something...
I appreciate the queue times for these instances can be long and waiting upwards of 30 minutes on somedays really sucks. But unless these same faction fights were friendly I think that the idea needs to be re-thought-out. I know people will throw arena in my face here, but dredgion and tiark are kinda different, the AP gain there is a lot greater.
I run a legion with 70+ members. We are all active and run these instances predominantly in legion groups everyday. We are organised and tend to get queued immediately. This means our chances of hurting your own legion is high... So what, half of my legion effectively has a higher chance of gaining ALOT less AP than the other half. Now how am I supposed to deal with that as a BG, my job is to make my guys happy and to help every member progress as easily and as quickly as possible.
I mean, change my mind. Tell me why I would rather hurt my own legion than wait 30 minutes. Time which we normally spend dueling or pvping open world anyway?
