I'm not really worried about the 40 units because I'm sure most will be similar and each faction will probably have a few unique units which will fall into one of the R P S categories.
If you need to put a cap on a unit you should be able to limit the unit without saying "rules". Like in NTW some units you can only pick a limited amount of in which case we should be able to do the same with some options without having to say over and over again rules to a game. It should say the limits in a box somewhere when choosing to pick a game and when you join.

Nothing more funny than joining a custom ranked match (yes I know I should host my own, but I don't care about rank I like to test peoples honor) and says no arty. The map turns out to be a bridge map (I haven't looked at all the maps yet) and not only that he has 10 arty (how cute). My army didn't even really get to make contact with his and was just incinerated by his howitzers. I don't mind the losing at all, but it just seemed like a waste of time all for some experience points which in the end means very little plus you just make a bad name for yourself (I want lots of stars they look so cool).

Custom ranked games = fail, but lots of people worship it for some reason and will do whatever means necessary to win. It just reminded me back in STW days where someone would host a bridge match with a timer on it or all the huge hill map edge corner campers in ranked. Dedicated servers with standard settings is the best way for ranked matches if you're gonna have them at all... not custom games.

What next... the spacebar showing unit end points and travel paths dose indeed show dots of the unit where it ends up, but just didn't in the demo for me. Something that's annoying is when you drag out a line with selected units... sometimes when you press the spacebar it's not the same as what you drew out (very annoying) please get that fixed.

Units need to be able to break up formation and reform back together when going around buildings and obstacles and not take these odd paths way out in the middle of no where.. sigh.

Running Running Running.. still a problem in NTW 10yrs later? Just add a toggle for units to run and march as well as keeping the double click and hitting R cause they don't always work. I would like to be able to have the Run toggled on and select a unit and give it an order and it runs to where ever I ordered it to go and not have to worry about a double click not working or hitting R and not having that work either and sometimes not realizing it until it's to late. Just one click when I have it on will do just fine thank you very much.

Also you gotta love Steam... I had the game for a week and already half the days Steam has went down, so I couldn't play or I've been dropped in the middle of a game? Something is wrong with that picture no? Steam isn't the best option and I'm sure we'll have the same problems with it when STW2 comes out... sigh again.
