@KaletheQuick I did some thinking on that, and there are a few options I considered. Set-up could be a good balance option, but doesn't feel very Aeon, since it's a pretty significant thing they don't have it. Having it be a hover tank also runs into the issue of hover is rather strong, and it could give them an unneeded edge in navy if they had a siege unit that could use it's main weapon against ships. My best thought was a unit that fills somewhat of a 'middle' ground between the harbinger and galactic colossus, since despite both being walkers they are very different, like there's a missing design step. Perhaps a heavy walker, using a similar design philosophy to the harbinger of being more expensive that it's counter-parts in return for being a stronger unit? It could out-range and out-damage the other siege bots, but have a low RoF and lack other weapons to make it shine as a siege unit.
It's a shame I have literally no idea how to do stuff with modelling else I would probably try make it myself.
