I just started an eldar army and I got the battleforce. I've modelled the dire avengers and I am starting to model the guardians. My question is, what weapons should I give the weapon platform, the wave serpent, and the war walker? I want a decent amount of anti-vehicle weapons to take out enemy vehicles, enough anti-infantry weapons to take down at least a decent amount of models from large squads (orks, termagants, guardsmen, etc), and i would prefer it if the weapons were long range. Also, what units should I get next? I was thinking rangers, swooping hawks, fire dragons, and possibly a close combat squad (striking scorpions, harlequins, etc.) to defend my troops in close combat.
