Eles mudaram várias coisas, tentando equilibrar as raças. Vai algumas coisas. Tem mais no site da Blizzard.
Humans: Brilliance Aura has been reworked, and is no longer % based. It now adds a fixed amount of mana per second to units under its power -- .75, 1.5, and 2.25 respectively by level. While it's just as effective with mass spell-casters, players will find it is less powerful (though still exceedingly useful) with Heroes.
Humans: Divine Shield now costs 25 mana, down from 75.
Humans: Blizzard no longer goes up in radius as the level of the ability increases.
Humans: Water elementals now last 60 seconds, down from 75.
Undead: Gargoyles' ground attack was substantially upgraded. They now do 21-24 damage, up from 16-18 damage. They also have less armor (3, down from 5), but also hit harder against air units, doing 51-63 damage, up from 46-57 damage. Note that they are still just as effective against air units as they were before, but their ground attack has been much improved.
Undead: Death Pact now costs 50 mana (down from 75), and can be cast twice as frequently as before (15 seconds cooldown from 30).
Undead: Lich Heroes now have far more hit points, as they now have 15 str + 2/level, up from 13 + 1.6/level.
Undead: Frost Armor is now an auto-cast spell which will target units under attack if auto-casting is enabled. Frost Armor also costs less mana -– 40 down from 50.
Undead: The Spirit Tower Upgrade now costs 160/40, up from 120/40.
Undead: Crypt Fiends' attack was slightly improved.
Orcs: Headhunters have more hit points (350, up from 280), but also strike more slowly.
Orcs: Stasis Trap no longer stuns friendly units, but has a shorter duration (6 seconds, down from 12 seconds). Stasis Traps, when they are set off, also destroy other Stasis Traps within their area of effect.
Orcs: Kodo Beasts now have 1000 hit points, up from 790 hit points. They also attack more slowly than before.
Orcs: Orc Barracks cost less lumber: 50, down from 70.
Orcs: Watch Towers now do 16-18 damage, down from 19-22 damage.
Orcs: Grunts now have 700 hit points, up 20 from 680.
Orcs: Shaman's attack is far less powerful. They attack somewhat more slowly, and also do 11-12 damage, down from 14-16 damage.
Orcs: Stasis Ward and Sentry Ward no longer inhibit movement or building construction.
Night Elves: Sentinel can now be removed from a tree with various dispels (Wand of Negation, Dryads, etc.), as well by attacking the tree with a peon or siege unit (previously, the tree had to be destroyed -– now it merely has to be damaged).
Night Elves: Mana Burn no longer affects units with Mana Burn (Demon Hunters, Satyr Soulstealers, Felhounds, etc.).
Night Elves: Thorns is now a %-based ability that reflects 10%, 20% or 30% of melee damage dealt by level.
Night Elves: Wisp's sight radius increased by 25%.
Night Elves: Detonate now does 225 damage against summoned creatures, up from 150.
Night Elves: Non-tree buildings now have 5 armor, up from 2.
Night Elves: Ballistae now have an "Attack Ground" command.
Night Elves: Force of Nature cooldown reduced to 20 seconds, down from 30 seconds.
Night Elves: Treants now last 60 seconds, down from 75 seconds.
Night Elves: Eating trees now gives a constant, non-stacking healing effect for 10 seconds.
Night Elves: Moon Wells now spend mana on health and mana replenishment separately. For instance, if you sent a 0-mana, nearly dead Demon Hunter to a Moon Well, and the Moon Well had 100 mana, your DH would gain 25 mana, and 100 health. Before, the Hero would gain 200 health and 50 mana. This change does not affect the benefits of healing a unit without mana.
