Hi every one Sorry for my bad english, this is not my main langage.
I'm absolutly sure all races will be available in Dow III (with Add Pack or quick extension, and I think too there will be a new race.
About multiplayer, I really hope races will be rebalanced, because at least one faction in Dow (until Soulstorm) is really OP to my mind. I think this is not a question of gameplay of the oppising player. Necron are absolutly OP race if played by a good gamer.
We can rush them at the begining, but :
1/ It can be difficult, impossible if the gamer is good and use lord or breakers
2/ In 2v2, 3v3 or 4v4 they can be protected by allies.
Obviously we can't win against them, but I find the fact that when there are necron in one team the difficulty grows in the opposit team isn't fairplay. The opposit team is allowed to rush. It can be exhausting.
It's a little the same with the Tau. Two race which, if not rushed from the begining, are instopable.
I want to give you a exemple. My favorit faction is IG. The last game i did was à 2v2v2v2. I was with a SM player. His base was near to a Necron base. Necron attack him at T3 WITHOUT Monolith. I send him my banneblade, two leman russ, one machigun team and commandos. Necron was full destroyer (so bye my tanks) and use his destroyer lord to capture my leman russ, so I had to destroyed them. Necron destroyed my allie base and attaqued my base. My autocanon began to destroyed his infantery and his destroyed. And what he just doing ? Nightbringer and Flayed Ones behind my lines. They attacked my machigun while his troops were shooting at me at other side.
So this faction
-can destroyed easily vehicule with Immortal T2 (not cheap) and Destroyers (which are in addition to this, very mobile on the map. Real tanks hunters).
-is the best faction in melee after Sisters
-have one of the most powerful firepower
-can capture ennemi heavy vehicule
-have the best commander of all faction
-can make his commander immortal during +1min (knowing that at this moment he hits 8 times stronger as his normal state)
-don't need requisition point, only energy with generators
-Makes his units invisible
-Stun ennemi vehicule
-And finally, what in my opinion is the icing on the cake, or should I rather say, the height of anything : relieve a dead army after a battle, and complete the ennemy for good before rushing to its base without the need to redo troops.
