i believe tos need something to reward the players that keep playing tos despite all and that way having another reason to login.
i think of something like connecting to the lobby and redeem your login reward then the player choose the character they want to give the reward.
the reward can be for consecutive days
it’s don’t have to be anything extravagant
by example, a amount of silver depending on lvl, a enchant scroll, a instance clear voucher, golden anvil/silver anvil.
and if they connect long enough they can get something nice like a few tp or a skill/stat potion reset.
