This is actually very true. Switching the designers (not developers) for a mod/game can actually result in a very different outcome. It's extremely unlikely that two people had the exact same design path in mind, and it would likely get taken in a different direction.
As I've mentioned, that isn't 100% the case. It's possible AoA will update as a mod, but the new thing on it's way is a far far better replacement. I'm not unveling details yet, because most "mod to game" conversions in the past from modders across most games have been an absolute disaster and it sets a really bad precedent. The notable ones that weren't were ones where there were giant amounts of funds behind the creation (see Dota, PUBG, H1Z1, etc). That being said, we won't be falling into that bad precedent.
