Let’s put it in perspective:
Riley said he wanted Normal Raids to be about on par with low level shards in difficulty. A low level shard can be completed (generally with some difficulty) by a new player if they’re persistent at it, and with some practice without too much difficulty. You also don’t really need good gear to get going on them.
So a Normal raid should be completable by a group of mixed-experience players who have +0/+1 gear. It should be hard for them, but something possible with the knowledge of the mechanics and some practice.
Boss 2 is managed in such a way that you cannot complete it with such a group, at least not without straight ignoring mechanics and just throwing down on the boss until 3/4 of the group is dead. The dps race on the adds, particularly how it switches off cycles from 2 dps cycles to 1 and then back again, makes it impossible. Fix that so the adds always spawn when the boss is shielded and you have two add-unshielded cycles and you should be good. It’ll still be hard, but it will be possible.
