I must not fear.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing.
Only I will remain.
Seriously though I have two things I'd like to see in 4e:
1) NOT using Star Wars Saga Edition system like some people on WotC boards suggested - seriously it *sucked*
2) Some thing simmilar to (not necessarily identical) ToB maneuvers for fighter classes.
