Witch at least seems very fragile when I pop open those breaches. Can't get a moment to restore energy shield.
:/
edit: To solve this problem (seriously, I die to almost every breach I open), I picked up flame surge to quickly attack close range. Now the question comes up... why do I even bother using scorching ray... only reason I can think of is that it looks pretty.
edit2: Now with further testing, I find even these changes are insufficient. Each time I open a breach that spaws more than just a couple mobs, I will die. Since reaching act3 on normal I ahve died in every breach. If nothing changes, I'll stop opening them once I'm past normal.
