So I like the looks but...are they supposed to be unable to be placed in most rooms in a base? Both the arch and the wall need a smaller model variant.
I think a better accommodation would be to make lairs larger to accommodate these items. Maybe more rooms or a way to adjust the pillars/levels in the base itself to allow for more customization. I think they were on the right track with the new larger room that the recent base layouts have, and there's no reason to limit the layout for pvp use when pvp is practically dead anyway.
