Skimming the video and the thread, I think some elements of the pets system are being overlooked.
In a nutshell, the pet system is essentially duplicating the process of pulling for new legendaries/mythics when they appear, using “tiers” to duplicate buying keys with gems while granting guarantees of small numbers of pets to incentivize each purchase. The giant tell of this is in the few seconds when the shop screen is scanned through.
From the video, we know that it takes 31 copies of the pet (around 3:15 in the video) to max out a pet. Thirty-one copies of a pet is going to be next to impossible to get from pure RNG alone, given the size of the pet pool and that the size of the draw pool will only get larger and larger.
So… enter Pet Rescue events. In these events, the pet pool will be limited to just the featured pet. One copy is guaranteed upon a full clear to unlock the pet at level 1. To “ascend” the pet, the player needs 5, 15, or 30 additional copies of the pet. Very similar to Godslayers/Siegebreakers, buying Tiers grants more copies of the pet to “guarantee” ascendancy (note on the tier windows where it says Pet times X, and then below it says Get X of guaranteed in the flavor text, with X being the same number). There’s also baskets, which appear to be random chances to get additional copies of that pet (likely gives food otherwise, which is close to meaningless if the pet can’t be ascended - hello, reskinned orbs of growth). It is best to think of baskets as Event keys that are locked to Pet Rescue mode used to try to pull extra copies of a given pet.
With plenty of pets in the pool, and a once a week selection, the devs can likely go an entire year before needing to duplicate the same pet’s event (again, similar to Godslayers/Siegebreakers). Which means, that if you like a pet and want to max it out, you have to buy-in on that pet’s specific event, or near forever hold your peace).
But… those bonuses are weak and lame, is what people are saying. They’re not wrong. BUT… they stack, and in the future pets with duplicate buffs will appear to buff those numbers further. And surely, there will be power creep with pets as well to encourage players to buy-in in the future.
And then… for those at the top, there’s the issue of inefficiencies. Because everything stacks with each other, the cumulative effect of non-maxed out pets will start creating power gaps. 1% missed there, 2% missed here, 1% missed over there because I’m trying to save gems this week… Over time, those inefficiencies WILL start adding up and will become significant in PvP/Guild Wars.
The devs know exactly what they are doing with this new pets system.
