I've bought this bundle with my main char who already maxed out the mount skills (speed, capacity etc). I thought I just could drop the lessons into my bank for another char of mine to pick it up and use it. Unfortunately I cannot drop it in the bank and this is a HUGE issue. I've paid money for it and ask the dev's to allow dropping it in the bank. I am sure I am not the only one with this issue.
