Last time around I posted my list of recommendations for the next revision of Eldar HQs. This time I'm addressing the coveted Elite spots.
Ah fire dragons... I love them and I hate them. They frequently fail me when I need them most. That being said, there really isn't anything I would change about them. The Exarch is a real winner, though I've never found occasion to use the dragon's breath flamer. Both of the Exarch upgrade powers fit nicely into the Fire Dragons' main purpose. No changes.
I don't think I would change this unit either. The weakest link in the unit's options would be the Death Jester, but I suppose I'm biased; I really like the old Citadel Journal test-codex for harlequins. Bio-explosive ammunition, heheh!
In 5th edition I rarely feel the need to field banshees. Even so there's little need to alter them. They are excellent at what they do, and the Exarch equipment and power options once again feed into the main purpose of the unit. War Shout may be a bit iffy - I don't think I've ever heard of anyone using it to great effect, and even if it did, dropping an enemy from WS 4 to WS 1 only means that the banshees will be hitting on 3+ instead of 4+.
<edit> Instead of the WS-altering ability, why not make War Shout into Furious Charge? Essentially all they are getting out of the deal is +1 Strength, but that is enough to make facing a charge by these dead-sexeh ladiez a truly frightening prospect.
Simple: Outflank in a transport. Otherwise, no changes.
Here we go... GET RID OF WRAITHSIGHT. Wraithsight might have been an effective balancing handicap in 4th edition, but in the current milieu, it's crippling. Wraith units are mechanical constructs animated by the souls of dead Eldar interred in spirit stones. Spirit stones are also used to man vehicles; they don't have to make wraithsight rolls to avoid Crew Stunned.
The wraithcannon, on the other hand, is excellent, as is their basic statline.
