I think that the big lack of interest from the community to the online function is due to the people that make that community. You don't find a lot of teens with tons of free hours ahead of them to play online games together. The EHM community is mainly made of adults who either have a job or commitments at university. Both are time consuming and can't really be skipped to play EHM. Sure, some people play at work

But globaly, people don't have that much of free time to play the game, and therefore it becomes difficult to find free time together for some online play. And as most of us just don't have enough time for online play, we simply just care about it, and prefer a better solo game.
If a poll was running between improvements in the AI and improvements for the online play, you'll see a huge win for a better AI. Same for an improved 2D engine or more tactical depth, or a more detailed approach to the training. The online interest is very weak in the community, even if it's certainly a very enjoyable experience. But when you don't have time for it, you just skip it.
Anyway, this debate has absolutely no reason to exist. The devellopement is on hold, so i don't really see the point of talking about what should be or not the best way to devellop the game.

It's actually a total waste of time.
