But now this new feature destroys the whole concept of attacking garrisons...
Please explain your thoughts behind that statement...
Maybe it never was the planned concept to let your heroes die on every single attack, just to enable you to attack with zero risk. Maybe you actually have to win every fight and take a risk by fielding more then just bronze.
The game mechanic to crack a wall with 80 pots instead of a real army is stupid and they should even work on that. It is quit common on our server that you get attacked every 90 minutes to slowly send your garrisson to hospital. Thats an annoying and riskless way to siege. Thumbs up for the change, especially combined with the shorter healing time for troops!
Any change that makes you play less is a bad change in my opinion
Well, it won't make you play less, if your heroes wouldn't have to suffer every single fight you take.
