What are the main things you want to see fixed from EB1 in EB2???

[Arkhis]

1) Battle Map Fighting (Yea they are elite, armored units, but come on, they are not supermen!)

What do you mean by this?

2) Campaign AI (I offer an army-less, money-less, territory-less faction peace for nothing and they refuse with the attitude that they can still kick my @$$!)

Diplomacy in M2TW is still as shit as in Rome: TW, so it won't be any better, I fear it's hardcoded. That's why people use that forced diplomacy mod.

3) Ending Date/Time period (Personally, I wish EB2 would be more "Imperial" than "Republican," but if it must be, at least go into it, don't stop at it's beginning)
*I think this one is especially relevant, for Rome did not stop growing until Trajan's days...

The game is not about Rome alone ;). Besides, it already has over a thousand turns, that's REALLY long.

4) Illyria (Like Aristotle used to say, if Gaul, then why not Illyria???)

They're still working on the new factions, though I doubt any Illyrian tribe will be playable. You should look for the criteria for faction-inclusion on these forums and see if they fit any of those.

5) Or for that matter Numidia, Mauretania, Belgae, Dacia, and Thrace! (These were all unique people with unique customs and heritages - I wouldn't put such "tribes" as Massalia, Crete, Rhodes, etc. as a faction because they only really comprised 1 single province/town and were part of a greater culture, not its embodiment)

Again, they're still working on new factions, but you should read the previews, 'cause then you'd know that: Numidians are in, represented by the Kingdom of Massylia, and Dacians and Thracians are already in EB1, just check out the Getai.

Factions are political units, not cultural.

6) New/more formation alignments... would be great to be able to deploy in triple line, or alexanders cavalry/phalanx, with a simple click... as the real generals of old used do!

Hardcoded again, I fear.

Personally, the biggest issues I have are with the AI, and those should've been fixed by CA, but alas, the AI is still bad :(.
