In regards to my hybrid list, Its just not the play style Im looking for, and it doesnt seem to be meshing well. It feels like im playing two seperate armies. I have my slow footsloggers trying to march 6" to the fight getting shot to bits each turn, and my fast skimmers already on the other side of table killing things but with no support so they die soon after. It just feels like my army isnt meshing together.
You can solve that problem by fielding infantry in two waves, where the front group runs, while the second walks, and/or by taking a linking unit. the former is probably only viable with a 2000 point list, but the latter could work with a 1500 point list, depending on how it is structured.
The only reason I consider Eldrad is because I can use mindwar to get rid of powerfists
This is unreliable in my opinion, given that most opposing models with Power Fists have higher than average leadership, so it is not worth taking him for that reason.
and his staff wounds on 2+ and ignores saves
Again, this isn't really worth it in my view, since he doesn't have a large number of attacks, and he isn't supposed to be in the list for hand to hand fighting.
plus he has a 3+ invul.
A Farseer is easily tough enough in my experience, so I don't see why this is such a significant issue.
So he is considerably better than a farseer
Very questionable in my view. If you play well, and have a good strategy in place, you won't feel the need to cast three powers per turn most of the time in my experience, and his close assault abilities are hardly worth the additional expenditure in points.
and 60 points more than a doom/fortune seer.
A regular Farseer with Doom, Fortune and Spirit Stones gives you a greater saving than that over Eldrad, and even if this were not the case, this is a significant saving in my view.
I was also considering adding a autarch but couldnt find the points. Im not to concerned about the 2 scoring units, Ill probably be keeping them in tanks most of the game.
Given that Storm Guardians are one of the best short ranged infantry killers in the Eldar army, how can you keep them in the Wave Serpents for most of the game? Tactically, it just does not make sense, since you will be wasting their valuable firepower, and you also need them in play to support your Striking Scorpions and Fire Dragons, so I find your strategy rather unconvincing here I'm afraid.
The strategy you are outlining is more akin to using the Dire Avenger/Falcon combination, so if you want to take the Storm Guardians, and I think they are a good choice, I feel you will have to come up with a more aggressive, albeit not suicidal, strategy, in order to make the most of their abilities.
and to get a 3rd scoring unit I would probably have to go DAVU falcon route.
Not necessarily, as there are other options, such as those which I mentioned in my previous post.
I hope that helps.
Edit: Regarding the alternative list, I'm not sure that it would have enough anti-tank without the Fire Dragons, while Guardian Defenders in a Wave Serpent are not an improvement on Storm Guardians in the same vehicle, so I suggest reversing that change. Holofields on the Fire Prisms also are unnecessary in my view, given that it is preferable for them to take fire at the expense of your Wave Serpents, and leaving Holofields off them may just encourage your opponent to expend more fire at the Prisms, thus giving your Wave Serpents an easier time.
