Just a short post, I think another thing the devs should do is increase the tactical move speed for the strong and deadly monsters as their slow speed is easy to exploit and it allows weak low level champions to giant kill these monsters and claim big xp and item drops, which consequently makes it easier to giant kill the next big monster and level up much faster than the AI champs.
I think creatures like trolls and ogres need a move of 4 and death demons and drakes need a move of 6, otherwise a champ with high speed and initiative can simply kite around them using a ranged attack or moving in, attacking and retreating before the monster can retaliate.
I took down a bone ogre using a level 5 Procipinee with the fast trait, a sacrificial dagger, a haste buff, and slow debuff - she literally had 3 turns to the ogre's 1! She was able to kick the ogre's ass without taking a scratch. Irane is also able to pull off quick giant kills if you boost her speed and initiative - she just runs rings around the monsters and shoots them 
By boosting the speed of these monsters it will shut down these tactics and this ultimately levels the playing field for the AI opponents as their channelers and champs will not beat these monsters based on an auto resolve roll.
