Follow-up as Bolt is leaving Latest pool
TL;DR - I’m saving all LTs and CP for ~10 months starting at the beginning of Season XXXI. If others wish to do the same feel free to come here for support and encouragement.
What? Why???
The 5* transition is a long one - best measured in months or even years for the casual player. The 5* release rate outpaces the LT/CP earn rate for the F2P player (and even most spenders), meaning that over time you will never max all the 5s since they will continue to dilute the classic pool. The latest pool, however, keeps just three characters at a 5% draw rate for each one. So the best chance to max a 5 is to be able to pull all 13 covers for them from the latest pool before they are moved to the classic pool and their draw rate is substantially reduced. This requires either a lot of money or hoarding.
Yeah, but…WHY??? Won’t you miss out on progressing the classic 5 characters?*
With three champed 5s (really just having OML/Phx champed) my roster really doesn’t get that much more competitive by adding a handful of 5 covers here and there. But if I were to be able to “whale” the three latest 5*s as soon as the last one is released it gives me a bit of a competitive advantage as others are slow to catch up. Since I can’t afford to spend that kind of money, my only other option is time.
OK, but how much time?
Great question (spoiler alert, I already told you it will take about 10 months, but here is the math…) I hit max progression in every PvP, and nearly every PvE (Heroics often get skipped, and sometimes life gets in the way). I have completed every single DDQ4 battle to date. I often place T10 PvP, and always get all CP rewards from PvE nodes. So between that and my VIP I earn about 8.6 LTs and 521 CP/season. At a 5% draw rate it will take an average of 260 LT pulls (13/0.05) to cover max a Latest character from the 5* pool. Theoretically all 3 characters from that pool would be champed together since you get the same 5% draw rate for all of them. This assumes an average distribution of covers across characters and colors which I must admit is a poor assumption. After 10 seasons I should have about 86 LTs saved and over 5k CP not counting any spending me or my alliance does, or any rewards from championing characters which will be good for 300 pulls. That gives me the 260 I need, plus 40 bonus pulls to help with poor RNG/streaks.
The other side is ISO. It will take something like 1.6 million ISO to take three 5s from 255 to champion, but I make anywhere from 20-30k ISO/day. Over the 280 day hoard I should bring in between 5.6 and 8.4 million ISO. That’s a ton. As I’m pulling all these 4 characters I will keep some stash of ISO on hand to champ 4* characters as well to make use of their covers and their champion rewards which will bring in additional LTs and also help make up for any bad luck I get (hopefully).
Prologue:
Relevant roster at start.
Other 5*s for reference.
I’m on day 683 as of the start of Season XXXI tomorrow, and this will mark the beginning of my Legendary Hoard. As you can see I have the first three 5s champed, and currently have no LTs saved up, and less than 20 CP. This is my starting point. I have 10 champed 4s, and all 3*s champed except for Beast.
Chapter 1: Season XXXI
My plan for Season XXXI is to first champ Beast (the only 3* I don’t have champed), and then champ all my 2s. I think I’m finally to the point where I can really start recycling the 2s now so those covers don’t go to waste. I don’t yet have the willpower to hoard ALL my tokens for the season as I know many like to do so hopefully by the end of the season I’ve got a nice stash of LTs and CP saved up with my 2* recycling factory up and running as well.
I recognize the timing of this is kind of terrible with SHIELD Ranks being unveiled and likely changing everything, but the basic concept I think will remain. Even if the SHIELD Ranks increase my earn rate, it will still make sense to hoard until I can pull ~300 Latest LTs at the same time, which is the ultimate goal. If I get there in less than 10 months I’ll end the hoarding early (and if it goes well start a new one). If it takes longer then I’ll wait. I have no interest in having 3 more 5*s at 7-10 covers each, that doesn’t help. Depending on how things are going I might wait even longer to build up a 1440 CP reserve to buy covers outright should RNGesus really bend me over.
I’ll do what I can to log my progress in here at the very least at the end of every season, or maybe I’ll update this post as each event ends or something like that. I’ve never made an opening video, but if there is interest I might try to get that set up for the final opening (or not, most of the ones I have watched have been pretty boring - so there would have to be a lot of interest.)
Happy hunting and good luck to all the other hoarders out there!!!
