Rouges are not the only guys who should be able to open high DC locks.
There are Trickery clerics and Bards to consider.
also there are plenty of character types from all the different settings that may not be full rouges but still have associated lore suggesting they may be good at one of the given rouge abilities... using Krynn as my example, Red Robes, Lilly Knights, Skull knights, Thorn Knights, Sirrionites, Zebiomites, Hidites, Sargonites, Sentinals, Kender, Gnomes, The Legion of Steel, to name a few, so I am content with the 1%
