I think it was that there would be Races added, Im not sure (or i don't) Remember the names of said, but it was discussed heavily with other members.
ETA was 3-4 months i think
With the addition of races Kainzo will add Skill points, So that Races actually have an effect on Classes.
With these Kainzo restricts some classes that you can play IE an ogre cant be a wizard or caster.
The additions are basic and simple for skill points/stats, Bigger the class the stronger/More health it has. IE STR (strength) and CON (Constitution) The leaner the class or taller, The more INT and WIS (Intelligence IE spell power) (Wisdom IE amount of mana)
The Lore behind most will be made shortly after the release I can guess.
THE BALANCE
Well with these additions, some think It may be hard to balance, That may be true, But To be quite honest, These Will play a minor role within heroes even as a big change. I highly doubt that Changes wont affect too much, Say like Each point in STR = +.5 Damage, You get say 5 points per level, Now lets calculate that with a Thief's diamond sword
120 Base STR : 0
122.5 STR = 5 level 2
125 STR = 10 Level 3
127.5STR = 15 level 4
Yes yes it may seem a bit op, But look at it this way, A dreadknight will only kill a thief faster if he does the same thing, adding to strength only.. And there can also be conditions like
If the player Adds 1 strength he/she loses 2 hp. ETC ETC.
The possibilites are infinite, and we wont know them till kainzo releases it.
