Your list has been selected for inclusion in the Big List of Eldar Lists project! You will be receiving a score from me using the 5/5 system as outlined in the Big List of Eldar Lists in the stickies on this board. Following is the critique I have given:
Background: 0
This is an example of why lists posted for critique need to be finished products rather than WIP. WIP lists [or works-in-progress] need additional input before they can be completed, so there is a lot of back-and-forth dialogue between members to this end. While this is a good thing for a list that's in development, it is very hard to offer a critique on a list that is still in development because it undergoes permutations. There is the inclination to not update the background material or the strategies, and just have readers assume that these are modified accordingly to the new army. However, one should never assume that others will know for certain what your new plan of attack is, or that your background material has been altered to match the new list or if it remains the same. Additionally it is hard to critique a list succesfully when flipping back and forth through different versions to get the full story. In the list above, which is the one I am reviewing, no background info is given except that the list derives largely from someone else's input. Not good!
Composition: 1
Even though the list is only set for 1000pts it is still decidedly short on troop elements. Given the theme at least one more jetbike squad would be nice, giving you some options for locking enemy units and dealing with a broader range of threats. Your list includes a Falcon and Fire Dragons, so is not as susceptible to the repeated weaknesses of an all-jetbike list, but you might have a hard time dealing with enemy hordes given your low model count. You have included units with good differentiation of primary roles.
Utility: .5
The reduction of 1 Vyper, 1 Shining Spear and the Withdraw power, and the star engines/second shuriken cannon on the vyper for the addition of a third jetbike team with warlock and cannon. Falcons tend not to shoot much, the star engines are unnecessary because the Fire Dragons in a falcon benefit from 12" deployment in front of board edge, 12" movement, 2" deployment, and 12" range, meaning on the first turn they can hit the enemy. On the second turn it becomes a definite, and this is the soonest you could fire if you used the star engines anyways. You are paying points for little if any benefit. A single spear is not so big a deal since your list indludes the Autarch, and the jetbikes are generally more versatile than a vyper, and typically more durable too. Also, the jetbikes delay the deployment of your Autarch, allowing you to set the spears and the Autarch together at a more fruitful position.
Flexibility: .5
Most of your units have the capability to handle any kind of target if played correctly. The similar unit types means you have incorporated a repeated vulnerability, but given the nature of your theme it actually isn't as bad as it might have been. Enemy model count is likely to be your toughest problem; fortunately, with the great speed of this list, it is possible to pick apart enemy opposition piecemeal, which evens the playing field a little. Great care will need to be taken to avoid early casualties.
Ingenuity: 0
Again, no mention is made here of your tactics, strengths, weaknesses, or even what tasks you intend to assign your units to. There is no mention of synergistic combos and no description of strategy. Add to this your mention of another member rewriting your list for you, and this spells trouble. Since a lot of the editing comes from other players it is imperative that you make known your understanding of the tactics, strategies, and weaknesses of this list. Otherwise, you are taking a weapon to battle which you have no experience wielding, and may end up beating the enemy's skull with a rifle rather than shooting at them.
Total Score: 2, indicating more work needs to be done
You take your biggest hits for not really providing an explanation for anything in your list. An army list on its own wins no battles; a great general with poor weapons can defeat an average general with great weapons. Be sure you understand your army list, and be sure to make readers aware that you understand your army.
