It's not about failing. It's about the check results being too random and too little influenced by character skill.

2d10 or 3d6 would create bell curve results which is the cool thing dice CAN do over flat percentages. But D&D is stuck on using the "iconic" d20.

If they insist on using 1d20, the skill modifiers need to be twice as significant as they are now.
