Amen! I got just got my first non-Classic 5* hero from HA10. (It was Alucard, which I’m actually very happy with; he’ll be my choice for upcoming Visiting Costumer.) The cost, wait time, and odds of getting a non-classic hero are really in need of being updated. An extra queue would also be nice. You have to figure the cost of the training/re-training as well as the opportunity cost. Recruits don’t exactly grow on trees, so spending 300 a week on HA10 may mean you don’t have the recruits for other things. I think they could essentially halve the time and cost and double the odds for a non-Classic hero or a costume (I’d actually more than double the costume odds, make it like 20%) in HA10. HA8 isn’t too bad, maybe drop the time to 2 days and reduce the cost to 50 or 75 recruits, double the odds of a non-Classic and add a chance at getting a costume. Troop training should also have the costs reduced.
In a nutshell, speed up most of the tasks, reduce the costs and improve the odds of something good(better than vanilla).
