Right I will go over a few changes that are coming that will effect ubers.
Firstly they are now effected by a change coming that will effect a few abilities, AOE Damage Dropoff. When applied to an ability this reduces damage the further the creature is from the epicentre of the hit (0 at edge full in middle). This is being applied to the ubers standard attack.
Secondly I am introducing a new stat - AOEResistance. If a creature has this ten if they are hit by an AOE but are more than 10 (very small) from the impact location then the damage is reduced by that percentage. Currently I am only giving this to black ants (20%) but I also intend on using it to a higher degree with Fire ants so they are not totally ruined by a single AOE. It also reduced the damage of damage over time effects coming from an attack.
And finally I am re-tuning there attack and abilities, making sure each one has a weakness of some kind and that all can possibly be killed by any colony (it will still be a costly endeavour to fight them with black ants, but it wont automatically be game over if one goes for you queen). I have re-balanced 3 Ubers so far, 5 to go!
