Myth #1 : Bosses have to be insta death mechanic driven or it's tank and spank - it's one extreme or the other.

Truth : There can be a compromise and there have been plenty of games for the past 20 years that have had fun and difficult bosses that didn't rely on overuse of these mechanics.

Myth #2 : Players asking for variation in encounter design want things to be "easier"

Truth : Some players want a varied play experience and some feel the current design undermines motives for attaining some current rewards and discourages or prohibits grouping options.

Myth #3 : The developers have to choose ALL one way or ALL the other

Truth : Devs can be flexible or create content for different types of play

... so if you disagree with the OP, great. Why do some people keep posting trying to argue with other players about thier experiences?
