Attacks have varied targets to make sure that there are other threats for non-tanks than just room-wide AoE's. Some ignore aggro-table completely (like, always attack healers, always attack DPS...but I think that Shiryuu at least have attacks that always attack tanks too) unless their primary target are not alive, others attack people with different aggro tier.

There are even bosses and mobs that completely ignore aggro. For non-boss mobs that usually is shown by a tether. If you see a mob tethered to another player and ignoring your aggro, then don't bother trying to grab their attention. You won't. There are at least three bosses that attack completely randomly, between every attack deciding who to go to (the earliest is in Quarn's temple, the golem, after he was "broken" the first time). It's not something you should worry about nor waste effort trying to stop.
