"There were too many tank and spank style encounters in the past, leading to players being bored. Now Blizzard is trying to ensure there is at least one thing for everyone in the raid to think about during the encounter, rather than just focusing on the boss as a target dummy."
Now let's look at that. The idea that a boss with multiple phases and mechanics means that the boss will be good in most cases. I don't completely agree with this. Some of my favorite bosses in WoW history haven't been bosses with a ton of mechanics, but difficult DPS checks. While I think that having these multiple mechanic/phase bosses is good, and alot of them are fun, I feel that the 'tank and spank' bosses with tough DPS checks are one of the most rewarding bosses to kill. I look at heroic Baleroc from Firelands, or Heroic Ultraxion. Neither of these bosses had tough mechanics to master, but one of the best things about them was having to learn to maximize your DPS and squeeze out every number you can, and getting that kill with a second or two to spare before they one shot the raid.
Having every boss be a simple DPS check isn't a good idea, but doing away with them all together isn't good either, IMO. Even once you overgear a Patchwerk style fight and it's not difficult anymore, I still enjoy a simple 'stand in one spot and pew pew' boss every now and then to take a break from all the hectic fights. I kinda find it relaxing in a strange way :P
Does anyone else share this opinion? Maybe I'm just lazy haha
