Nord Invasion about to fizzle out.

It could be moved to the siege engineer tier or even better removed in a current state and reintroduced with less materials required for crafting (ppl who already have an hc could be given a shc or just cash as a compensation).

This would be great.  Then it would be, by order of crafting mats: Normal, HC, SHC, Wall.  It makes sense to me, and I think would be a great option for mid tier players.
