Thats not really a overview. Why not just implement a page where the last games are listed and you can view the game stats again (there are so many ppl who actually love stats^^)
“Multiplayer is a mess” is kinda correct. There are so many points all over the forum here. Not really bugs but something what a good multiplayer mode should have. It just feels like they stopped developing in the middle 
I not really liked the multiplayer ui/lobby in AoE3 but in AoE3 DE it is even worse. There are some good additions (like the no block option for treaty) but is it thought-out? No it is not…you can not see anywhere (not in the game browser nor in the game lobby itself that the game is hosted with no block). And are these missing things bugs? Do not think so…
Oh not talking about the gameplay or the ranking system here. Thats maybe fine…but if you wont find the right games then gameplay is secondary^^
