Which Crimson Guardian Training Ground is Better?

I timed my EXP/ hour inside, and it is definitly lower than what I get outside. The map layout is tricky. The CG's magic attack was making climbing those ropes very frustrating Though map sharing would probably work way better there.

The outside map is so hard to party on. Usually when I split that map I go on left and somebody else goes on right. But it's so hard climbing up those steps all the time. I've tried going on top with a stronger person on bottom once, but my spawn was slow, and that caused the one at the bottom to lose a lot of EXP, probably because of the fact that I just wasn't getting the spawn I needed to reach my full potential.

Though on the old map, it works okay if a sin/ bowman just wants to snipe at the top and I stay on the bottom row and I'm not actually partied to them

Prior to cwkII (changes to CG's hitbox that makes this currently too dangerous/inefficient), I would sit on the right stairs and snipe with PA fury while berzerked, and a hero or bucc would take the top/left. I could also solo the map fairly effectively, but recent changes made zerking nearly impossible there without large HP reserves that I don't have yet, so I can't effectively go back until 14x. yay himes...
