I don't want to discourage you but a footslogging Eldar army is, quite honestly, going against how the Eldar are meant to be played. Eldar are fragile, but they have speed to make up for it. A footslogging army needs to either have tough, durable troops, or a lot of numbers. They need to be able to take the pounding that they WILL recieve as they trudge across the table. Eldar do not have durability nor great numbers. By footslogging, you are now fragile AND slow. I believe it is time for you to update your army to match the general playstyle of 5th edition, which involves much more mobility than previous editions.
