"Oh orks thing can be instant respawns! Then they don't have to be as good as the other races and we can farm their worthless butts in the hundreds." -quote about ideas foe balance from literally every non ork player ever eager to expand their e-peen.
Come on, no-one is advocating orks to be crappy instant respawns. I am advocating slightly faster respawns and a stat buff but to a lesser extent than what the marines get. This won't make them the whipping boys because orks have good firepower and will be tough. There is even a possibility that they will become the strongest faction, but more likely it will just be a really good balance.
Just halve the TTK on Eldar and im fine, im not fine emptying a clip at them and they just run up and knife me to death.
There are a few things that need a definite nerf, that you can't bring up the other factions to balance with.
Eldars are damn fast in melee. I understand this, this is lore thing, i agree with it. But for the khorne's sake, give SM their lore thing- damn POWER ARMOR, i mean HEAVY armor, so eldars have less armor but speed, and for SM more armor and keep their current speed. This will be fair. Orks... well, i think they should be something in the middle.
Eldar also fracked up the balance in Battlefleet Gothic...and other games, starting to sense the pattern here? Id say add Necrons and only pit them against necrons.
