The Eldar army is made up of specialists. Unlike an army like the Space Marines, each unit is really only good at one thing. Their close combat units are very good at that, but are usually unable to shoot much of anything. Likewise, their long range shooters are capable of pouring lots of highly accurate fire on the enemy, but fold as soon as they get caught in an assault. As a result, you need to support units with each other and play very tactically to get the most out of them.
Here is what comes in the Battleforce:
1 Eldar Dire Avengers Squad (5 models)
1 Eldar Guardian Squad (8 models)
1 Eldar War Walker
1 Eldar Wave Serpent
1 Eldar Heavy Weapon Team
This is one of the cheaper boxes at $95. Bought separately you can get the same force with a few more Dire Avengers for $146.75.
I will not attempt to tell you how to paint Eldar in this small space. The army will not necessarily have a unified color scheme since each unit comes from a different Aspect Shrine. As a result, each unit should be painted in its own scheme in order to differentiate them on the tabletop. For the best look, focus on keeping clean lines and bright highlights. It is OK for Imperial Guard and Orks to look sloppy, but not these guys.
- This all depends on what kind of force you want to start putting together. A Farseer with a Council is good as they are effective in combat and the farseer can boost the army with his psychic powers.
- Buy transports for your units when possible. If they are protected in a vehicle, that will go a long way to mitigating their low toughness.
- After a few games, begin building up where the weaknesses lie. For shooting, get some Dark Reapers or a Heavy Weapon team. For durability, get some walkers or tanks. For close combat, get some Banshees or Striking scorpions. For mobility, get a unit of Swooping Hawks.
To be successful this army has to focus on what makes it good. They have good mobility, ballistic skill, and initiative. Ask yourself how to increase those attributes and avoid their weaknesses (low armor and toughness).Also, Harlequins are cool. Buy some and learn to paint them so they look like the picture on the box.
