-Positioning is key when fighting around mobs you're going to skip.
-Do not wait for abominations, bring the next one before the one that is being killed is about to die.
-You can save downtime by avoiding the skeletal zerg after defeating Ramstein by fighting him inside the slaugther house at the steps before Baron.
-Bring Major mana pots and Major Health pots to use as downtime savers.
