So I've switched from Spite to Blood Magic on my Reaper. I miss the additional damage, but people are getting wrecked in some of these events and I've noticed a reluctance to WP when dead so being able to rez and heal like a madman does more towards ensuring the event suceeds. The last event I did was the Legendary Mordrem Wyvern and people weren't CCing so people were dying left and right. It was nice being able to get them up without putting myself in too much danger. Helicopter transfusion is the best
I'm still in VB and I haven't seen everything yet so which events are locked by masteries? So far all I've seen are the canopy night events which need gliding 1. I'm pretty sure the noble, itzel, and Laranthir are all doable without masteries and the pact ship is annoying without gliding 1 and itzel 1, but still can be done.
