I for one found that if i have to always stealth a nuisance just to discover secrets and traps. Why not separate out as a different skill or maybe you don't need to stealth for you to discover traps and hidden places? After all it all depends on the skill ranks you need to have to discover the trap or secret areas anyway?
Of course you still need to stealth if your intentions were to sneak up past an area or for thieving. Thoughts?
