As a space wolves player i love pods. but you have to pick your targets and drop your pods carefully. 1500pt games i hate cause i just cant get that extra pods in, 2k are where its at cause i get pods and support.
If you are finding that you cant crack an eldar army with pods and grey hunters maybe look to forgeworld books. Some Conversion beamer tanks are mean! str10 Ap2 large blast... yep!
anyways i feel some people over look the power of a lone wolf... take that long fang squad you have give them a rhino or razor back, put your lone wolf and his puppies in the tank and as your pods are off making one hell of a mess the lone wolf can safely cross the board and eat anything in its path.
if your eldar enemy brings a wraith lord well you need a rune priest! because a force weapon is your greatest friend to multi-wound enemies. one fail and hes gone. i often times if i know my pod army will be facing a
MC with multi wounds or somthing that i just need dead in one turn will put a rune priest either with a squad in a pod, a squad in a rhino, OR (my fav but i dont get alot) is a rune priest on a bike with swift claws... remember the first and second turn of the game your pods will be making a mess pulling your opponents attention off of whats cross the board. Personally if you bring pods, bring them
TO DIE. do not invest heavy amount of points, go for numbers on this one, the more you have, the more you will stay allive for that next turn. so your pods are basically one shot wonders.
Also Forgeworld offers a very nasty dreadnaught drop pod, which allows the dreadnaught on the turn it arrived to stay in the pod! since the pod is open-top he can fire in any direction from inside his nice 12AV 3HP shell. So that long range multi melta can be nasty! then second turn he can assault out of his pod. Also first turn the pod arrives you he casts shround i believe on the entire pod as well as anything that is standing on its doors. so drop that pod in first turn, with some grey hunters who can stand on his pod for that nice cover save. (this means he has to choose where his ignore cover saves go... the mean guys running across the board... or the grey hunters/dreadnaught right infront of him).
honestly i have an awesome time destroying eldar, very rarely do i have a problem with them but you need to go all one way or another. Space wolves (with forgeworld) can out shoot eldar as long as you stay long ways away. because you use your rune priest to buff long fangs/tanks with rerolls and ignores cover now his jink and other eldar shenanigans are out the door. As well as that rune priest down range with pods could cast
FNP, and so on.
I have had a kick taking a rune priest, long fangs with multimeltas/hvy bolter or hvy flamer and casting
FNP, relentless, and it will not die on his squad and watch the long fangs just nom nom nom through enemy armour and troops thanks to split fire

(hvy flamers are awesome!)
