I think they should just ban bots outright, allow a maximum of 2/3 accs per IP or something like that (think PVU), and leave quest potions as they were, nowadays quests in bronze feel underwhelming.
I´t isn´t fun to struggle and win the required battles just for a single chest, which nowadays don´t even have cards in them lol (until they update reward set that is).
That´s my, @trenloco ´s opinion. And I´d love a centauri for that lol
