I was actually just raging about this to my friends last. I have lost count the amount of time I have used RtL to try and close the gap on someone just to somehow completely overshoot them in almost the complete opposite direction or get myself killed because I am stuck as an lightning ball in mid air.
Two others that I have noticed and may be bugs:
Mist Form: It states in the tooltip that you invulnerable for the duration of the spell, but I have died countless times to DoT damage during this form, if this is intended, then the tooltip needs to be changed to state that I think.
Armor of the Earth: It states that it breaks stuns, and then further makes you immune to those effects, but I recall being stunned and being unable to break stuns with it.
