You're kidding right? Their card (+15% to 10% combat to toma, aenna and mantlet) got nerfed and they get -5% hp from aura. 100f may seem cheap but it also helps running out of hunts faster. Aenna should work somewhat like mace will do now.I like the changes to the Iroquois, but I think aenna may be a little too powerful now. With the warchief aura and their plethora of cards and base stats now rivaling those of the cetan bow (and a cheaper cost and better age 2 shipments), I think these guys may be a little too strong.
About sioux, they got no boost for their eco and they got a HUGE nerf - war dance, siege dance, wakina, wc, no more axe riders braking the counter system. Plus the -100w to slow them down. The only boost was the raids, but the cav got slower too :\
About iro ff it will be different (no more fp spam, more kanyas and tomas) but I think it still breaths.
About port, I think the RI nerf was an indirect boost to them. They won't suffer much from it because you already had to have goons along with caças.
