Joining a party – Get invited as a healer, despite your preference for DPS. Proceed to stare extremely hard at the screen until the Rogue and competing Enhancement Shaman who are both after your mace leave the party.
First Boss – Scream at your thick tank to “PICK UP THE DAMN [Insert race of ranged opponent here]”, because you can’t heal them when you are dead. Twice now that has happened, twice being the sum and total of the times I have healed this instance. Pick.Up.The.Damn.Troll.
Second Boss – Gnash your teeth at your DPS because you don’t give a damn if you can heal through the flashy light, it’s the principle of the thing. Don’t look at the blinding exploding guy is on the same tier as don’t stand in the frickin’ fire.
Third Boss – Cry to [deity/enlightened being of your choice] because why the hell does the final form of the last boss have to be so much of a bitch to heal and OMG DEATH LASERS I just died again rage.
After you win – Mutter to yourself because despite the numerous upgrades that you could have got for your main spec, none of them dropped, indeed, no upgrades for anyone else dropped, and all you got was some flashy healer belt, further putting your off spec gear ahead of your main spec gear in terms of quality.
I don’t like Trial of the Champion. It’s an evil place. Whilst Kazura waltzes around in her nice new gear earned from there, I get my face blown up by the ridiculously difficult to heal final phase of the Black Knight and mourn my lack of shiny maces.
Disclaimer: Screaming and crying not advised. Gnashing and Muttering certainly advised.

Trial of the Champion can be really annoying when you are trying to get something. Drops from a particular boss seem to be fairly rare (about 15%), and for the second boss, you only have a 50% chance to even get that boss at all!
at least there were lasers ^^….
Ah yes – the old:
“This boss does AoE Damage. Now. I can AoE Heal. OK, you’re all going to stand almost exactly OUT of range of an AoE Heal but still be IN range of AoE damage. What, exactly, do you guess will happen in this precise scenario pray tell?”
Thus, almost every time I’ve been I’ve let the noob ranged DPS die a horrible death and keep the tank who actually does more DPS *anyway* alive ^^
Nice post!
