Rework miss chance in PvP

The chance to miss vs. targets significantly higher level than you is excessive and should be tuned down. When a player 10 levels above you attacks you, it is all but impossible to land even a single spell. There are times where I'll deplete my entire mana pool without landing a spell on someone.
Instead of having this miss chance be 90%+, it would be better to tune it so that the miss chance is capped like it is vs. a raid boss. That way, a player of much higher level who attacks you still has an enormous advantage, but at least now you have a shot at outplaying him.
So to be clear, what I'm suggesting is:
This is a change that would go a long way towards making world PvP more challenging & enjoyable.

So to be clear, what I'm suggesting is:
- Miss chance against enemy targets of similar level stays the same.
- When there is a large level difference between two players, cap the miss chance for spells and physical effects at 17% so that the high level player is effectively a raid boss.
