It's probably like other Rite heroes and he can only uses his ability and do nothing else, so not worth it unless you need to colonize a ruin, which honestly doesn't really happen. I'm not too sure why it's there, I guess if you get sacked maybe, or if you pick Necrotect in the early hero choice and unlock it really early when there's still ruins around.
Cities did help with research. I only started expanding on turn 70. Until that, I was sitting on Khemri and the little province that had savage orcs the entire time, wasn't much of an issue but it did give me terrible research rate. I unlocked tier5 in Khemri around that time too and built all the tier 5 buildings at once since I had some saved gold because I had no cities to spend it on. Now I'm fast expanding with powerful armies and just rolling over everything. I'm using a taxi army to recruit the good units and deliver them to my good armies and I still have an army sailling around for treasures. I'm about to finish Arkhan and then I'll be waging war against the other TKs to take control of the desert.
The "good" thing about how the autoresolve seems broken with TKs is I still have to fight stuff, even though I completely stomp them, but it's still fun and doesn't take long.
Construct spam is pretty broken though. There's I think too many ways to increase their limits, other than the expensive tier 5 buildings. Like you can recruit a Necrotect that has +1 base, and they themselves can be spec to give another +1 and then you have some lords in the dynasties with +1 and then you just end up with a ton of constructs which are free. And while they weren't as good in 1vs1 unbuffed, with a Necrotect in the army it easily gives them an advantage.
