It's stupid to argue about metrics like progression and try to tie it with the lag, because it's very clear that this game would be borderline faceroll easy if it didn't lag in such an unusual way. So yes if tomorrow someone bought out SE and just replaced the server architecture you'll probably have 10 times the player beating the content compared to before. That doesn't mean the content was tuned correctly just because the lag happened to make up for a lack of difficulty.
