Some suggestions on Ironbreaker

[Foondin]

City:
I would propose to add renown and ability trainers to city while siege. Think it would make cities more dynamic and interesting.

Ironbreaker:
"Oathstone" CD from 30 sec to at least 25. I think it would make this ability to use more often and it would make IB a bit more offensive.
"Avenging the debt" needs a check on working on oathfriend as I am using it and cant see it working properly. It would be great if this ability would make you and your oathfriend immune to slow affects to 5 sec.
"Stonebreaker" needs buff at least to 50% --> 300, 600, 900, 1200.
"Rune-etched axe" CD from 10 secs to 5. For now this great ability does from 40-70 damage and it's not so usefull as it can be
"Stubborn as stone" kinda useless for now. If +50% attack speed would affect oathfriend not for so much would be nice.
"Anciestors Fury" doesnt stack with potions and other abilities. If it stack it wouldn't disbalance a lot as melee dps have their max strength cap.
