I have noticed a much bigger aggro to spells now since the latest changes. Both Necro and Druid in Droga Mines specifically. The aggro is so bad that just sending my pet on a target with no spells, the target will pull the healer merc after 1st heal. The pet is taunting as usual. Both Necro and Druid aggro after just 2-3 spells where it was more like 5 before. This just happened with a few days. I have been playing for the last several months consistently.
