I wish to make fortifications for my harlequins but with the rule on wysiwyg really limits the design choice but what I had planed was get a fortification with a ADL or some other with a possible gun point and stick my Solitaire on the gun point due to the army lack of anti-air and the solitaire having 9BS will most likely always shoot down pesky air targets also with blitz getting up the field should not be a big problem unless rolling really poor.
So what building's could I use and what I had in theme was ruins of a eldar fashion.
