I took my summoner into Plaguelands in Liche form. Skeletal Burst feels a bit stronger against the normal monsters. Against the Liche King it actually felt worse. It procced the Poison Spirit from Plaguebringer less than before. Killing the LK took way longer than before wearing the same gear. Before I was able to equip Sss'Haa's blade and let the summons do the work. Now that there are fewer, they don't even scratch him. I had to use Plaguebringer to slowly poison the big lug. Very, VERY slowly. Yes, the skellies are tankier and yes they do more damage against normal monster but against bosses, numbers are our biggest advantage.
