Shorter cooldown for class change pls

I know there would be already some topic with regards but still hope this small suggestion can be heard. Would be great if at least bring down the cooling period to 12hrs instead of 24hrs for class change. Kinda pain to wait. Indeed sometimes like using one class during pve or certain event but pvp have a better skilled class vice versa. And in my case mainly i would sometimes love to test different class abilities as an exploration which is also enjoyable and makes me keep playing DI. Somehow the feeling of being hold back playing multiple classes. Thank you.
