This might be a me thing- but personally, I really, really dislike the timer system for breeding specifically- launch started at 1AM for me, so already I need to stay up that late just to birth my pups now.
but also for companions. I especially dislike how these companions all have different resting periods, it's really overwhelming to keep track of.
These have the potential to do the time creep thing- where it starts off okay, but each time I'm a little bit late, the time I have to come back gets later, and later, until I'm staying up way too late just to keep up.
I think rollovers will be better for this- when it comes to companions, can we just merge how many rewards we would have been able to collect in a single day from them, maybe some will need reward reworks, but I already need to keep up with professions- these are fine as timers. But I want my wolves and their companions to be something I only have to worry about once a day.
