I think that's what the Guardian Jetbikes are for. Not only that, they can contest most objectives because of their crazy 12"+36" moves. You are right, this is different.
Ahh ok so thats what GJB means... lol. I dont play Eldar, only against them, so I had no idea.
I agree with the fact that guardian range... sucks. Using them as a stand + Shoot unit doesnt work well. Yes, anyone withing 12 of that landing pad will die, but people can just ignore them if they want to, and if you spread them out then the other squads will die b/c weak. When I use my brothers Eldar (we sometimes switch armies because why not...) I normally put them on backward objectives and use DA as my forward assault troops (support of course by banshees and dragons, and the occasional scorpians).
In addition, if you outflank your Scorpians then there is the high chance they will get massacred. My brother tried that (w/ karandras) against me, and I took them out with Dev's. He even had cover...
Fire dragons are really good. You should use them. They have a 100% (not statistically but from experience) of blowing whatever vehicle they're shooting at (if its not a flier).
Scorpians are less good... Theyre only really good against heavy-light-infantry armies... And even then if they cant get into combat (or they kill the squad theyre assaulting) then they will die.
Sorry, why are the Guardians fearless?
