I agree with you, but partially Gdot.
The game is planned to be "finished" in October. Personally, I have felt the effect of improved/more servers but none of their actual code optimization has helped me, and reading the steam discussions I'm not convinced it's helped many people either (obviously there is a bias there, people are more likely to be playing rather than posting if it works, but hey)
Three months from gold means we can pretty much expect things to be in pretty much their final state, and unfortunately that means for things like: the interaction, movement, animation, sound and performance, I think the safe bet is: what we see is what we get. Now, that's "fine" I don't begrudge them their success, the player base is amazing but I'm not sold that this is the transcendent cultural moment that many people are making it out to be.
True, they certainly have things to work on. I don't think its fair to say the game has finished being updated or reached its final form, especially considering the new update announcements as of this week. If the game will reach the pinnacle you are describing (legendary status) - time will tell. It certainly is a fun and captivating game.
For those who need a group or want to play with other players from the COH2 community, I created a group.

Today was the formal launch of this group, we already have a large contingency of coh2 players and a TeamSpeak where we all hang out (which any of you are welcome to pop in and join us). Find info on the group page. Wow!
