I agree with cow, realistic balance changes should be kept as subtle as possible, so i'd be happy with just:
- Frost Nova Cast Time reduction and faster Ice-to-Fire mode change.
- Regulus and Demon Assassin base speed up to 6.3.
- Random QoT buff that makes her go Out-of-Mana less frequently (god is she mana intensive ).
I won't agree with a Lord Erebus Base Speed reduction, he already has problems chasing targets after bites, and he's actually "kinda squishy" (lowest base armor of all demigods), he relies on awesome HP regeneration skills, without his speedy movement he would get kited to death by ranged chars, and ub would eat him alive. What i'd actually nerf is Bite HP gain (most omgwtfbbq OP skill), that's what makes him unkillable along mist-batswarm.
I'd only agree with an UB speed reduction to 6.0 if Inner Beast Movement Speed Increase got a buff: if it gave 5/10/15% movement speed increase by Inner Beast rank i'm fine with a UB base speed of 6.0.
