Please Reconsider 30min lfd Debuff

As a fresh 80 this debuff is brutal. Seeing as how I not only need the badges, but the gear from these dungeons, this is really slowing me down. I've run into a number of problems that have forced me to leave a group. These range from DPS posing as Tanks to que faster, DPS that are used to raid geared healers and pull aggro like crazy, and general dbags who are just unpleasant to be around. I'm just not geared enough to handle the first two situations, and I pay money to avoid the third.

I understand the reasoning behind the debuff, but there has to be a middle ground. I felt that 15min was more then enough to discourage group dropping. 30min just makes me log out. Yes there are a million other things to do, but I've already done them on my main. I've truly taking a liking to healing and would like to stick with that on this toon. Dungeon running is what I pay Blizzard to allow me to do, and I'd appreciate a reduced debuff time. 15min, even 20min is fine. 30min is an entire dungeon's worth of time and a bit to extreme in my opinion.

I'm also open to any suggestions and ways to improve my spec if youre so inclined. I've only played DPS classes before this so if you feel the need to flame, at least be constructive and tell me what to change.
