Well I suppose I will start, since I already started on another post
1) Split the army books.I think this only relates to Marines, Eldar and Slann/Necron (which I guess will be done anyway when new models appear).
Basically I don't think you need the Chapter specific rules in the main marine list. Separating them will give us the chance to have a look at all the chapters as and when we can and we won't have to continually update the marine book.
Speaking as an eldar player as well, I don't particularly want the Dark Eldar stuff in the same book. Split them off and make the books half the size, and it again allows each races book to be looked at separately if need be.
2) Reduce the graphic intensity of some of the books.As much as the book layouts look nice, sometimes the amount of stuff going on on the page and the layers of graphics just gets to much and this all leads to massive files sizes (I have Orks at nearly 90MB and Guard at over 50MB!) which can cause printing issues and slow download problems.
I know Primarch said he wanted something that looked nice and could be bound up like a proper book, but if you look at all the GW books (rules and codices) their pages are white or beige, very little back ground images, they break things up with nice borders and lots of colour pictures. You don't need all that colour to make the book look professional and nice. For me the marine book looks good, pail watermark which doesn't take away form the information, simple colour palette, but still looks professional.
3) Remove the reference to army cards.People don't need them anymore and most people don't use them with the army books and everything listed in tables. At some point in the future we might go down that route again, I know I have looked into making some, though it isn't a quick process I have found and most probably more trouble than it is worth in the long run as they are more of a "nice to have" thing.
So since we don't use them, don't mention cards. The best word I have found to replace "cards" is "formation". So rather than Company Cards, Support Cards and Special Cards, we have Company Formations, Support Formations and Special Formations. It is easily applicable to all armies.
3) Space Marine Vets are too cheap.Another point I have raised previously. I think they are undercosted for what they do. 50pts more than a tactical detachment (100 more than a tactical company) for double the CAF, increased morale and Elite. I ran the stats through the points calculator that was posted a few months ago (might not be wholly accurate but gives us an idea), and that says vets should be about 100pts more than tacticals, so I could quite easily see the cost of a detachment bumped up by 50pts and maybe the company to 1000. Would have to see how this affects Terminators to.
4) Smaller drop pod formation.We can drop companies in, but I think a smaller drop pod formation for detachments should be available; it might help make dreadnoughts more viable as well. I was thinking along the lines of a Support Formation of 4 Assault, 1 Support and 1 Deathwind for 100pts. This would allow you to drop a dreadnought squad somewhere or a vet detachment with chaplain ect.
5) Titans should be able to engage multiple enemies in combat.This is something new that I have been thinking about.
If a titan charges into combat it isn't going to just fight against one stand of the enemy, it is going to mow down hordes of them as it stomps, kicks and sweeps its way through. So rather than 1 on 1, when titans engage in combat with anything smaller than say a super heavy or knight, they are considered to be in contact with all models within "some number of" cm (distance to be decided) and will fight a round of combat against each. We could add that the anti personnel weapons will only affect those in base contact with the titan rather than everyone within the combat distance. This might make people think about arming titans for CC and sending them into the fray rather than just sitting back as a weapons platform.
6) Sternguard / Vanguard Vets.Something else I have mentioned on another post is the introduction of different veteran types since they are present in the marine list these days. Something for the optional book maybe.
7) Updating of the marine formations.Again, something for the optional book. New era marine companies follow a different structure for their companies compared to the old style. If you have looked at EA at all you will see the company formations are different to what is in NetEpic. Allowing a different set of formations might also tempt EA players to try NetEpic as they wouldn’t have to change their armies much. How this would work with other races, don’t know.
Think that is enough to start with
Matt
add few more orders: it's been 20 years we play with 3 orders: Charge/Advance/First Fire, maybe time has come to think about few new ones that would add variety.

Maybe time has come to complete the project
