haven’t read the entire thread, and haven’t gotten the poll. But here is my take on the idea of a subscription plan.
I am a 4* transition player. I have 4 4* champs and several more 4s at 12 or 13 covers languishing below lvl 200 for lack of iso. I have about 25 3 champs and have been slowly champing the stragglers (all around lvl 120). I do not yet have any 5*s in a usable state, though my best (phoenix at 2/2/2) is close.
Even at $9.99 per month, the package is entirely unappealing to me.
There are really only 3 resources in the game that really interest me at all any longer:
(1) Iso to champ my remaining cover maxed 3s and 4s
(2) CP to spend on Classic Legendary Tokens (My OML is only 0/1/0)
(3) 1k PVP covers for prized 4*s (still need covers for top tiers and like JG, Iceman, Cyclops, Nova, Quake, Rulk)
(note: Regular LTs and tokens are nice, and occasionally give me a 4* cover that I need (like the random Heroic Token last night that gave me a Rulk 
), but they are far too unreliable to be of any real interest. Classic LTs aren’t great, but they are the only way to get OML now, so they remain a high priority.)
Taking those three resources in reverse order:
With 4 champed 4s, including an IMHB and a 4 thor, I can basically get 1k in any PVP even that I choose using strong/fast teams like imhb/if and IM40/4thor. So that resource is already covered (pun intended), but I could use more strong 4s to help me get there easily every event.
the 1300 PVP CP reward takes too much time and HP to be worth it for me. So I rely on PVE and daily rewards to get CP. it’s a slog, but the best option available for me. 9cp a month just aren’t enough to interest me when PVE grinding will yield 39-64 a week. (note to demiurge: the solution to this is NOT to raise the bar on CP grinding in PVE to make 9cp a month seem attractive! That will just make me stop playing PVE, as i did for the first few PVE scaling tests.)
Finally, 10k iso/month is a pitiful sum for me. My iso needs are well in excess of 2million, and that number will hit 2.5mil as soon I pull 13th and final covers for antman, carnage, and IW. An extra 333 iso per day does nothing for me.
So overall, this package is not really compelling for me at all. It doens’t enough enough of the resources I truly care about to justify its expense. Perhaps if it offered 100cp,350,000 Iso. I would consider spending something like $10-15/month for 5 classic LTs and enough iso to level a 4*.
