Switched over to boss rush last night because I decided I want a mageblood for my two main builds (SRS and manaforged storm rain).
Couple questions... do I need to stand around and wait for Maven to cast her spell and the other bosses to spawn? I'm running these maps with a 60M-ish dps SRS build and if there's any skulls up the boss gets deleted instantly. Reason I ask is because my screen is covered with so much shit going on that I can't really see a second/third/fourth boss spawn (which also dies instantly), and all I know is that in my first ten maps the only thing that's gotten past my loot filter is a Cortex and one random red map. No other good maps, no invitations, not even any currency.
Not sure if the Destructive Play method is actually better, since it requires you to get either a large stockpile of at least 10 different maps that are suitable for rushing, or use shaper guardian maps which are a bit pricy and much slower to run than, say, Bog or Mesa or JV. With Exarch you just farm the same two maps over and over (that should drop enough naturally to sustain it) and it seems like the lower overhead/trade site hassle might make for more overall profits.
