GM interference in arena games.

Situation:
I play afflock/priest in 2's for weekly points. We ran into a mage/warlock today.
The warlock was at 25% and the mage around 20% when I got feared into the wall where I didn't have line of sight of anything. The mage/lock team used this chance to heal back and killed my priest. However they couldn't cast any spells on me. The only thing they can do is auto attack, flame orb, and pet attack. Being a lock (even without any kind of regen), I popped demon armor, made healthstones, and basically turtled up, trying to force the game into a draw.
After approximately 35-37 minutes, a GM decided to interfere and ports me into a position where the mage and the lock can freely kill me. My team proceeded to take a loss. I did ask him/her nicely to wait until the arena is over to take any actions, yet he/she ignored my request, citing that it's unfair to the other team. Normally I wouldn't mind, but after almost forcing a draw to have my only chance taken away from me, I'm compelled to make this post.
My number one question is how is it unfair for the mage/lock team when they essentially removed the dps from the arena. Since they had the advantage of removing me when killing the priest, they should also have the disadvantage of having to kill me using auto attacks, pets, and flame orbs. It's not like locks have any self healing anymore, aside from healthstones. If the mage/lock can kill me within the time frame, then fine. But since they can still attack me, the GM should not be allowed to interfere when I can force a draw, especially when there was only around 5 minutes left in the game. By removing me from the game the GM is essentially extending his/her bias and giving a free win to the other team. At the very least the GM could've reset the arena or forcefully exited both teams from the arenas.

Here is a screenshot of the conversation:

What do you guys think of GM interference in arenas?

PS. It's not about the points, because I really don't care about rating in 2's at all. It's about why the GM is allowed to be biased towards one team. If you want to say don't play lock/healer in 2's, well it's my money so I can play what I want. If you have problems against lock/priest then you just need more practice as they are probably the worst 2's comp ever.
