So I went to Rock Garden with a Human Rogue to try out the spoons. I got lucky with a WONAFYT glyph, and prepped a glyph magnet to get PISORF.
Basically what Darvin said. The layout could be
very unforgiving, especially when it comes to bosses.

Though I fear I have lost the newbie perspective... I'll do a few Purist runs to see if more physical-inclined classes would have problems with the tight corridors when I have time.
