Been playing the game a bit and have a few thoughts on some features/ lack of features and so on.
First most of the factions don't feel Fleshed out, simply put with the exception of the Imperium, Chaos, and Nids all of the other factions feel lacking. Most hard hit are the Necrons and Mechanicus. Consider merging the Tau fleets too with the Battleships from the merchant fleet changed to grand cruisers cause right now they are under-powered. The problem of fleet diversity is compounded by the next problem. It should not be hard to add new ships to the other factions, if you don't have ones that fit make some up.
Lack of diversity. Too many ships in the game are to alike. For the most part except for weapons all ships in a class of a given race have the exact same stats. Please devs change this up I want there to be more to choosing a a ship than its weapons. Again this problem is made worse by the next issue.
Lack of customization. Frankly the one part of the last game I liked most was the ability to customize your ships their captain skills and upgrades. Now both the skills and upgrades are fleetwide and this is a big mistake. You really have to have the ability to synergize the skills and upgrades with the ship or else all we are going to see in multiplayer fleets composed of the exact same ship class. Also the sub-factions have absolutely no effect on gameplay and that was something that was promised in the deb blogs so it better effect not just some modifiers but real differences like upgrade and skills choices and even ship classes available.
As you can see from the first three items in this post that a lot of the problems compound each other and unfortunately will kill the game if this is the release state. Frankly I'm returning my copy if these issues aren't fixed. Given the game was delayed 4 months I'm rather disappointed at the readiness of the game, this is what I expected the ALPHA to look like not the Beta with a month to go to release.
Below are some minor issues that I have discovered.
Eldar don't use lascannons, their called brightlances
Dark Eldar call their lances Darklances (did C.S. Goto write this?
the middle mouse to turn doesn't work and re0keying it doesn't work
