Ideas

Launch with all currently important community maps, as seen in the Voobly and DM patches.

The EE ELO algorhythm rewards beating low ELO players too much, leading to inflation. It would be great to have seasonal leaderboards and/or rating decay to keep activity going.

Allow us to connect with each other in the game itself.

Not having hotkeys for upgrades forces us to click these. Not cool!

Attack move is very ineffective - it should target each unit individually on the closest enemy, and have leashing behavior so enemies don't get chased across the map.

A very practical way of handling large groups of selections, such as a control group with all your production structures - for example I can press tab twice to bring up the training UI for my fortresses, which are the third building category in my selection.

No stats should be hidden. Achieve parity with text mods as a minimum, but ideally provide hover states when available.

The different formats should be considered for different leaderboards.

We should be able to view other hosted games and the chat channels while we are waiting for a match both in matchmaking, and in a private room.

Award XP for playing matches, scaling with performance. At level ups, unlock inventory items such as profile avatars, avatars, player card images for load screens, emojis, skins etc

Create a player profile window to show win rates of each god - if I click on Zeus in the dropdown, and 1v1 supremacy in the matchmaking filter, show me my win % vs all gods in 1v1 supremacy ranked. Also list win% per map separately. Provide in 1v1, 2v2, 3v3 (playlisted modes). Do not fetch data from custom games as they create noise. Filter for seasons if those are a thing.

Allow players to enter a party to form a premade matchmaking team.

I think in the spirit of balance and competitive play we should implement a 1 map ban rule and a 1 leader ban rule. This will not only strengthen the competitive nature of the event, it will also make it more fun with new and interesting match ups. I think this rule largely needs to be applied in the BO3 rounds specifically but I do think it would be beneficial to the BO5s and BO7s as well. I have been forced to play fissures at the start of almost every single one of my series and it is a horrendously balanced map. Right now in the meta, ship is pretty distinctly S tier above other leaders, some people may disagree with this, which is why I advocate for a 1 leader ban per player in a series option. There are 16 leaders to choose from and I think players should be able to vote with their ban what the most broken leaders are and what the most unbalanced maps are. Please upvote this if you wish to see this change happen in Meta Plays Tournament play.

This has been suggested elsewhere, but wanted to officially get it here. Really any variation of team game events would be fun, but maybe logistically challenging.
Some ideas:
- Having a “regular season” of one matchup per week that then feeds into tournament seeding at the end (similar to voobly champions league)
- Team games probably better on voobly due to extra lag on EE
- Clans of 5 players that must swap out players after each win in a series (or some other rule for encouraging bench play)
- 2v2 or 3v3

So ive been thinking too, i think it would be a good idea to try to add new tournaments, like empire earth or age of empire tournaments, or test it at least to see how it goes, i think this could be a very nice adition and could bring public from other games to know the other content meta plays already make

It would be nice to see a tourney with no player restrictions and no map bans.  You can then see players, using their best civs.  The best quality games!  

Skirmishes are for low level players, and for players who don't know their skill within the tournament scene. To encourage new players to participate, players that come in first should be barred from playing in future skirmish events so that new players will feel more at ease thinking they can place in these tournaments, and to prevent the same people from winning these tournaments. 
Participation in skirmish events has been minimal recently. A $5 or $10 cash prize to the top player may incentivize players to return to claim first, or a chance to be casted could also cause players to compete for that opportunity. Skirmish events are important for inviting new players into metaplays tournaments, such as stream lurkers, and while they haven't had the best turnout recently these tournaments have quite a bit of intrinsic value to the player base.
Perhaps new casters that join metaplays could be tasked with spectating these tournaments?
Skirmishes obviously aren't as high stakes, so unique gameplay or other attributes should be focused in order to hype up this type of tournaments. Players that do well in skirmishes feel empowered and try to compete in monthlies, just like a customer returning to a business they had a positive experience with.
There's a lot that could be done with skirmishes, it would be a shame to see them go because of low turnout.
 

Being able to ban a map from the map pool during tourney matches
In this way, maps in which a God is extremely dominant are avoided.

My idea is to make a new category of tournaments, but one wich doesnt consist of very good players, but actually low elo players, im inspired by a series made on youtube called "low elo legends" by t90official, the aim is to have lots of fun watching regular or bad players playing and seeing meme plays or something, i think it would be a very nice adition.
