Now that looks very interesting. Though there are some keeps that enjoy bad positioning, e.g Ellyrion keep, any chance of portals that make moving from SL to Ell a bit faster? For both sides hopefully.
Some other problems that might arise from new keep locale exchanges; Destro to southern Reik keep defence, damn many hostile mobs on the route. (especially since T4 keep defences now includes ranks 16+)
BC will become somewhat harder for both sides unless portals added with reverse keeps.
Caledor might become more nightmarish, since Destro might have hard time reaching current keep, which if turned for Order, will be straight between their Cale-DW warcamps.
Well remains to be seen, but I like the current KV skaven tunnel system very much, hopefully we see those little rats spread their filth to other zones too.

-Effective Level (bolstered or otherwise) is now taken into consideration when checking to see if an NPC can see through your stealth.
Does this fix WL pets/Squigs from sniffing you through stealth once the missile is target locked?
