Minions:
50% damage reduction in instances,
-50% chance to draw threat in instances.
25% additional damage reduction to AoE attacks. (75% total)
Minions always attack what their master attacks
Minions will not attack on their own and draw no area aggro (considered neutral while not in combat)
By instances i mean dungeons.
Pets:
30% Less damage in dungeons
Pets immediately focus targets their masters targets unless told otherwise
20% increased damage reduction against aoe (50% total)
Keep in mind this can be made to work ONLY in dungeons / instances and to a lesser degree out in the world(probably just the AoE reduction) and not at all in PvP to avoid imbalances.
What do we think? I think this is a pretty solid fix to useless pets / minions in PvE dungeons.
