Differences list between Armored Princess and Crossworlds?

[Vilk]

I wonder what is the exact list of differences between the original AP campaign and this same Campaign played in Crossworlds?

I understand the question could looks silly, but my problem is that I have AP in my native language and it seems Crossworlds will never be released in my native language. So for a first play I'm looking to play AP. But I'm not sure if I lost a lot for this original campaign.

For example:

• New units: Ok but how many, which one and what they worth?
• 13 New spells: Ok but what spells? When they become available in the campaign?
• 50 new abilities and skills: That seems huge how is this even possible? Skills trees aren't already almost full?
• 13 new spells: Is there a list and description?
• Are all those new features available in the AP campaign or some through the two other campaigns only?
• 70 new items and 8 new sets: Well again that seems huge, is this really change the gameplay of the original campaign?
• 7 New quests: After the original final or before? And if before how the additional xp provided is managed?

All in all I wonder if I'll make a burden to play Armored Princess without Crossworlds or not. And no need try sell me any I already have them all.
