1) Damage values on specific moves require fixes.
Examples:
Gladiator deflect. - too strong
Conqueror's heavy - too weak
Jorm - too strong with the current damage values and his ability to drain stamina ==> result of buffed unblockables through hidden 100ms lights.
Highlander - relies on heavy attack damage, but they are on par with assassin's heavies who have better offence with lights.
etc. (there are other heroes who have problems with that)

2) Overall damage of light attacks is too high, when combined with stamina and recovery changes.
This forces people focus more on spamming attacks instead of using bashes, heavies, etc.
Also, it makes some heroes with soft feint or fast lights with less telegraphed animations tough to deal with at lower skill levels (or maybe even higher): aramusha, shaman, berserker, etc.

3) Heroes with 600ms lights are in big disadvantage, since now they can't trade after receiving light attack. So they have to either a) block b) dodge (dodge-attack) c) hyper-armour (not fast enough). Whereas most heroes can just light attack after receiving light attack.

4) Revenge/health values on dominion.
I didn't get the issue here, cause I don't play dominion on TG.

5) People generally like the idea of promoting faster more offensive combat style. So, it's a good start, ubi. So, please, just before making it official, make sure that all heroes are treated fairly. Some of us prefer to play only 1-2 heroes.
