I prefer the original faction idea(s). To be honest, they sound more fun and more original. Just doing CTF and Iricia the entire time sounds quite boring and seems repetitive. But this is just my opinion. I had Factions in the mindset of Raiding each other's Faction Planet for a reward if you successfully raid, or successfully defend.

Red Faction raids Blue Faction. Blue Faction warded off Red Faction for set time (whatever each raid lasts for). Blue Faction earns set gralats and exp!

and vice versa
