While playing WoW.
I was a Dwarf Paladin, in the olden days when it meant much suffering, slow progression, and almost no attacking virtues.
I met another player and we decided to take on a Troll temple to finish quests we were both doing on our mauled own. We did not even have similar quests and could not share them.
We were 2 or 3 levels lower than the average of the inhabitants of the place. All yellows and oranges.
We went up, and the word slow cannot convey the degree of protracted progress (progress sounding already sarcastic within this mention) we experienced.
We finished his quests some 4 hours later, and commenced mine.
We reached the top of the place and found the Troll-ess that had to be dispatched.
We circled in with such care for a misbegotten approach would be cataclysmic, since we could ill afford ANY kind of extra aggro.
With all antagonists but the Troll Witch dead I jump on top of a stone altar to wait for her. Click without noticing on some thing laying on the stone block.
I only discovered it was a captured Orc Shaman, obviously there to be rescued in a Horde's quest, when it started pounding brutally on me, after I had clicked the wrong button while it was selected and I had begun hitting it instead of only inspecting it.
The domino effect is needless and cruel to recount.
