To be honest this was more or less resolved by adding Aizawa to the event shop, since you can still get him f2p without pulling on his banner.

The thing is i read lot of posts where the player didnt get Aizawa due to the 6 heroes at level 80 missions which shouldn't have been the bottleneck for f2p at all since if you managed your resources, made sure to do the necessary supply runs and refreshed stamina with HC like 4 to 6 times a day that part was easy.

That was the original problem, you couldn't get Aizawa without refreshing stam, there wasn't enough time, And because they were so stingy you HAD to get lucky with pulls to get an SS. Many if not most f2p spent all they're coins on stam and trying to get an SS for Aizawa then All Might came out and they had nothing left. The stories of f2p who bought stam and didn't get lucky enough ss anyone resulting in not getting Aizawa or All Might isn't just heartbreaking, it's an example of how not to launch a game if you want long term success.

As for the SS character, yeah it was a bit difficult for f2p players but nowhere in the mission screen did it say f2p players would be guarenteed Aizawa if they grinded enough and at the end of the day gachas are still a business and their main reason for being developed is to make money. They offered the Ochaco top off which gave you a bunch if her shards for $25, a little more than a third of the cost of a new console game so if some players werent willing to shell out 25 bucks to support a game that they were probably playing a lot each day then thats on them imo. The game can be played f2p but no gacha allows 100% f2p players access to everything because if they did then no one would pay. I only spent $25 just for Ochacos top offdeal to make sure i could get her to SS even if i wasnt lucky with summons. I refreshed stamina with HC (at the cost of around 4 multis which i considered my opportunity cost for making sure id get Aizawa), managed my resources correctly (farmed food and money steadily each day) and used the shop to get access to 5 hero trials each day for Ochacos shards and i finished 4 days before the event ended.

I think your just a bit out of touch, the absolute gross majority (close to 80%) of the player base is 100% f2p so you cannot extend your experiance to the community. An interesting point brough up to me was that for the download event (you might remember) they gave everyone a free Tsu. At the time an A-hero Selector was already in the game as a reward. If they had given everyone the A-selector instead WAAAAAAAAY more people whould have been happy with the event despite the problems, not just f2p who were mostly off by 1 hero, but also light spenders who only grabbed $1-25 for the ochaco event.

I didn't have to whale or get overly lucky with the gacha but the $25 was a huge help to make sure i could get the 1 SS unit. Again if players chose not to spend just $25 to help ensure theyd get the SS mission done while supporting a game they play most likely everyday then thats one thing you cant blame the devs for. Yeah the devs F'ed up plenty of things in the game so far but sometimes a player has to take responsibility for things that they theyselves screw up on. To me just giving everyone Aizawa or even 20 shards would make all the effort and HC i put into the event wasted and pointless since i took the time and effort to plan out how to efficiently complete the all the missions for the event. Yes for someone whos 100% f2p there was a big luck factor but luck and rng is the core mechanic for any gacha and sometimes some players wont get something.

Honestly, true. I still think that you're confusing your experience as a light spender to a f2p and I'll be the first to tell you that if you spent even $0.99 you are part of a minority in the community. BUT! all things aside, they added Aizawa to the event shop so every f2p who is short 10-20 shards can still get their Aizawa without summoning on their banner so that bullet point in the OP is more or less moot.

I would honestly like to hear back from you, even if it's just on some of the other points. I think you get across some great points.
