Most boring faction to play as

[Celtic_Punk]

pfffff, you cower behind your phalanxes and such. The casse are true warriors! And actually put up a fight against the romans!

[Apázlinemjó]

The Casse isn't really a hard campaign, you are isolated and that tells everything. It's fun, if you want to build up a strong barbarian economy and army, before you hit the other factions.

[A Terribly Harmful Name]

Koinon Hellenon - despite having a certain fondness for them, their roster is bland, boring and terribly anachronistic and weak. Nothing like a pike phalanx when you're playing Hellenes, and that's what they lack the most. And cavalry, especially cavalry.

Sweboz - Terrible.

Saba - Never went past turn one.

Ptolemaioi and Seleucids - Big Empires, not fun.

Karthadastim - I'm better off destroying them than commanding them.

The Best:

Romani, Arverni, Makedonia, Epeiros, Casse, Sauromatae, Baktria.

EDIT - The order above is my order of preference. The important aspect to notice is that I was never fond of pike phalanxes either, despite finding them a necessary evil for Successor states; my favourite part is the Successor Cavalry, otherwise the flexible and fast heavy infantry of the Romani and Gauls eats them for breakfast all the time.

I love all, I just get bored after I have dominated the world and there is no faction to challenge me.

If you battle with the same tactics you get bored as well.
For Hellenic factions you get bored using hammer and anvil all the time.
For nomadic factions you get bored using rinse and repeat or hit and run all the time.

so you must change your playing style. For example after I have dominated persia and mesopotamia with mostly Pahlava, I immediately change my battle tactics from classical rinse and repeat to a hybrid of hit and run and hammer and anvil.
Namely, I send HAS to soften the enemy. then enemy engages my pandadapoi phalangitai that pins them, then after the inferno of HAS the remaining enemy troops they are piece of cake for my cataphracts
so change your playing style, if you stick to historical realism or house rules, there is no fun mate
like : If you bored with slow moving phalanxes just increase the time speed...

I find the elutheroi in my Casse campaigns aggressive. I've been sieged many many times on the first few turns.

But Casse is a great challenge but it depend on the player who like challenge or peaceful, slow expansion. She has many good infantries and even romani elites are no match for them.
On the other hand, As I am a cavalry maniac, I have never played with them.

Casse starts with neutral to Eleutheroi, so you don't need to worry that they don't let you to grow peacefully. The AI factions won't bother you, you can concentrate on the rebels - wipe them out, build a "safe haven" then invade Gallia. Casse is the easiest barbarian faction, as the Gauls are forced to fight eachother and Rome, while the Lusos end up dead against Carthage, while Swebóz is isolated too, after a little growin' they get into a trench warfare with Rome and the Sarmatians.

Believe it or not: Koinon Hellenon (but that also my favourite faction!!!)
End up doing the very same thing when the campaign starts... kicking Kydonia, reinforcing athenai, and massacring Korinthos... then moving up and doing a really big mess as quickly as possible against those Makedonians and Epeirotes.... and when u concentrate to the war, Pantikapaion, Emporion, Chersonesos, Sinope, and every "Greek Cities" sent their emissary say they are on your side now.... Waaarrrggghhhh......

But they are really funny everytime i play... just need some improvement, and "add_unit" for Makedonian ai

I don't understand how people have trouble with Casse. In my current campaign taking over the islands was a breeze and after that I had a ridiculous income. I waited until 200BC to attack the mainland that way I could build up my cities and actually face developed favtions (that didn't work out too well, AI factions still seem just as weak with some being larger than others)
The only reason I'm not swimming in mnai is because I have three stacks of elites and a navy of 10 ships. If it wasn't for that I would easily have several million mnai.

pfffff, you cower behind your phalanxes and such.

Er, no. Look to my signature and you'll see that I play mostly as Getai and a bit as Romani. No phalanxes to be found with either. I hate them myself.

And it seems like most people agree that the Casse campaign is rather easy compared to those of other barbarian factions.
