I like normal better, at least for now because the game bugs out plenty of times, and correcting it quickly is often the difference between life and death.
Some things that come to mind:
Abilities not firing, often times my heal/pounce, requires me to move and fire it again.
Pathing bugs on attacking certain towers, where my DG decided to go around through all the defenses to hit it.
Auto attack/Auto follow bugging out on the targets I assign.
Pantheon is normal, so is skirmish, and the majority of custom games.
I don't often have games take more than 30 minutes either, and I feel that is about right for an RTS.
