Solution to healers not dpsing in dungeons

[Akelya]

I think I will quit Healer too. Especially since I just had a Tank who blamed me (Ilvl293 and WHM), to heal less than a 310 AST during an Expert run where I had barely time to look away from the HP Bars and he apologised for "watching the news and getting distracted". He rushed into the last boss battle while one of the DPS was into a CS. I waited outside with the DPS, because I think it's pretty upsetting if you're doing a dungeon for the first time and then you are going to be locked out of the final battle (And it will take so much longer on the boss too). Of course it was my fault that he stood in the boss fight alone - "You shouldn't be causing wipes only because someone is in an CS" - Err, excuse me, I asked you nicely to not rush into the boss fight yet and obviously waited outside. And then blamed me because the dungeon took 27 mins instead of 20. I'm out of words. Are there any reasonable tanks still out there? As it seems I am only getting those with huge ego issues and rude gestures.
