Well let me see the monk PL averages 42 damage in 20 attacks versus improved crit which allows 1 extra crit in 20 attacks which doesn't do 42 damage with CE on and probably won't generate 42 damage with PA on. That's assuming a 0 fort mob (considering all the fort going around IC is the obvious loser). With earth stance IC actually seems like it may be worth considering but as people seem to agree the rogue PL is probably weaker than the Monk PL.
you obviously underestimate Wis build monks. most of the time I don't need to put my threat gear on.
