I've run with several self-proclaimed normal mode groups. These are the same groups that needed the nerfs to Horridon's add health and Council health in order to down them. I feel that this is the type of group that Blizzard intends for normal modes to be tuned for. They will not down Durumu in its current state.
As far as I can tell from your previous posts, you think this boss is overtuned because everyone has to be alive the whole time to beat the enrage given the dps in an average normal mode guild.
How is that a problem? Should Blizzard tune encounter's assuming 1-2 people will be dead for most of the fight? Should normal mode encounters be possible to 8 man for a normal mode guild with great dps?
I mean, this sort of thing is exactly what casuals asked for; multiple threads were made complaining that a group could, say, do the mechanics of garalon perfectly but still wipe to the enrage (that's a close paraphrasing), and how that shouldn't be the case for normal modes. And now, it isn't. If you handle the mechanics properly you win.
How much further down is there to go from here? Players didn't want to have to dps properly, so the dps checks were lightened. Now you don't want to dps properly or do mechanics properly?
I mean, I'm not even against the idea of targeted nerfs but this seems extreme.
