Did a search before making this thread btw. I cannot believe that there are no current threads discussing Eldar Rangers.
One of the biggest imba units in the game, imo. Tier 1, inexpensive, monstrous damage to infantry (all except Necron), breaks morale, FoF, cloaked. Too good for cost.
I've seen eldar players produce nothing but two guards and one ranger squad, for all of tier 1. And they actually get away with it because of the insane imba of that Ranger squad.
This is a very short first post because I believe the answer is simple... nerf damage, totally. No damage from Rangers at their current price. They should break morale but inflict no physiical damage, not for their price. Either jack up that price to 60/5, or even 70/5, or no damage, especially not for 40/5.
