As it says in the title. I'm building up an eldar version of a bastion, and want to use comparable eldar weaponry on it. I would like to be fair, and match somewhat with the general eldar theme. That may translate to it being AV12 though if I were stick with the maximum of wraith bone.
Looking at the Imperial bastion it has heavy bolters and the quad gun up top. Not sure what the comparative Eldar weapons would be. Should it be a firestorm set up above. That could match with the same vehicle if it ever hits the open market. However the Imperial weaponry is so much stronger at
str 7. Can't even pen a space marine flyer with scatter lasers. I imagine Pulse lasers would be the closest to comparable. Slightly higher strength, but half the shots. Make it a twin linked pulse laser, if the shot or two does hit and pen, the
ap 2 makes it more likely to do damage with the +1.
Scatter lasers are more comparable to the heavy bolters I think, slightly higher strength, comparable range, higher rate of fire, but a much lower
ap. The next weapon I would compare would be star cannons. Lower rate of fire, although the ap2 makes it a little over the top. Cost wise Shuricannons are about the same as most Imperial Heavy bolters when upgraded on a vehicle. However, it's much less range, and less on the
ap for the same cost. I suppose that would be about right for an eldar bastion.

Perhaps a pair of twin linked shuricannons that can cover 180 degrees? The range seems rough being only 24". Let me know what you guys think.
