Easiest Faction for Campaign?

[athanaric]

and I'd like to say that bactria is far more threatend than Lusotania in the early game but when the worst is over probably one of the most potent factions.

Baktria and Casse both have a very difficult start but become very easy once you've managed to beat the nearest enemy field armies and take one or two provinces. With Lusotannan, you have to either disband many of your troops after the first conquest or blitz like crazy.

that said Sweboz have the worst economy, getai the widest troop selection

Nomad economy is even weaker. They can't even build proper ports in normal situations.
Getai have failsafe troops and a good starting position, which is why they are the easiest barbarian faction, right from the start.

I would advise not to play with 1.1
The up-to-date version is 1.2+fixes, see this for information about installation: https://forums.totalwar.org/vb/showthread.php?t=80270

EDIT:
you can't continue 1.1 campaigns under 1.2, it is not save-game compatible

sorry I meant of the barbarian factions, the nomads sometimes een seem to not have an economy apart from looting^^
