Few hours? I am waiting since I skipped the day before the new patch ( goddamnit ) to create the new one, and respeccing for strategus is just dumb. You spawn far away from where you want to be at 95 % chances, and it takes days, atleast 4 ( What happened to me, atleast twice already ) to reach the position where I want to be.
The cooldown shall be there only for the main, and I'd also lower it a bit.
