All discount sites need to be removed probably. At least 90% of them. For construction and alt even 10% is too much.

I have won one game when I had Summoning Circle - 60% blood discount. I had 100 vampire lords, ice devils, arch devils, demon lords, heliophagis...

I had an epic game where I had Ultimate Gateway and I was fighting for victory against Lanka with blood40 site...

Game like that are totally unnatural. They break the game. They make it interesting, sure, but when you get the site and you are at least medium nation, it's almost like "I win" button. Or rather cheat code. And other players still play the game, not knowing they have absolutely zero chances of winning.

Sites like that should only exist when others know you have them. It's not possible at dom3. So it's best to leave these sites out of the game. They can still be placed by mapmakers, so you can use custom maps with those sites at well known location.

I think you got straight into the heart of the matter. When known they won't break the game. When kept secret they are horribly broken.
This can be addressed by house rules requesting that anyone encountering such a site report its location to the game thread. This will actually serve to further spice up the game - imagine the pandemonium when all players learn the location of the "holy grail"

EDIT: All that said I'm still against removing the sites - well except maybe alt. as mentioned before - If we go the path of removing random mechanisms that dare to give some advantage then where would we end up?- Probably with an increasingly balanced & boring game.
