Would you expect a BMX rider to have their seat up so that they had to lean over to get a toe down, or a mountain biker that rides a downhill bike in the bike parks or maybe someone that uses their bike for dirt jumping??? Of course not is the correct answer.

The OP indicated "I can't touch the ground with either toe without tilting the bike to one side." Not being able to touch your toe, not foot, "toe", down without tilting to the side at the lowest saddle position is no way to have a mountain bike set up. Certainly you would want to have the seat post range be broad enough to set up a position where your leg was almost straight at the lowest point in the crank cycle but you also want to be able to slam the seat to the bottom when you are faced with a long steep descent covered in roots and rocks. The OP is barely able to get a toe down at the "lowest" setting, this is not something he/she should get used to.
