These aren't new... but still present...

1) In melee, several melee only attacks for monsters are ranged - notably... the spider devour attack, the ogre attack (not the boulder) can hit anyone, anywhere... and several other monsters attacks.

2) Also in melee, casters don't seem to need to follow the rules for spells, even champions if on automatic.  For instance, Varda's thunderstrike attack requires an an empty square and she ends up on the empty square when completing the attack - ON MANUAL.  On automatic, she seems to be able to just call it down.  The wizard (pointy hat guy) can do the same thing.  It looks like thunderstrike, but he never moves and doesn't require an empty square.  The same thing for Pounce and drakes who (I assume) are using pounce... they can use it without moving.

3) When the SK casts a spell in combat, it seems to always say Tortured Haste...
