Most irritating enemy faction?

[Silver Rusher]

I just though I should bring this up. Playing as the Egyptians I found that the Seleucids just won't go down no matter what I try. Their army balance is just too good- to defeat them you need a very balanced army as well which the Egyptians do not have until quite a late stage of the game.

The Scythed Chariots are overpowed IMO. I had a 7-star general with a huge and well valoured army. I crushed a lot of the enemy captains, but got massacred (well I suppose it is a bit over-exaggurating, but still) every time the enemy army had scythed chariots in them. Many say Scythed Chariots are underpowered, but I strongly disagree.

Anyway, just vote on who you think is the most irritating, backstabbing, least diplomacy-friendly, or just hard-to-put-down faction out there. Choose wisely... and make sure to explain why you voted.
