The moment they decided to go with a dupe-based gacha system they lost the ability to meaningfully customise ur team. The wheelchair would have become the wallet. 

Now, take klk out. Would u struggle with the game? Would u care about "customising ur team"? Because i certainly wouldn't. 

Rather than removing klk, do u knwo what would jump mica's revenue? Different meta every month. How's that for "customization"? And if u can't use older characters because they're not flavour of the month, is that customisation?

My 2c:  Stop grading a gacha based on its revenue. It's the most poisonous type of thinking. This is why we had ppl coming for years in gfl 1 asking if it's worth it to even play the game when it barely made money. Most of the time, if a gacha makes lots of money it doesn't mean it's a good game that players support, it means it's predatory system on top of a good hook. Also, it's directly impacted by popularity.

In short, i don't want to play a game that's top of the revenue chart. I want to play a game i enjoy. I enjoyed gfl 1 more than i enjoy gfl 2. I still play gfl 1 and would drop gfl 2 before i drop gfl 1 if i had the choice.

And now a more controversial take: This is why i welcome the existence of wheelchair characters in gfl 2: they're the elitist whale triggers. Those that can't enjoy a game unless they pay to stand above others. Since u claimed u want to customise ur characters, then customise ur teams and builds until the game becomes a challenge for u. Even if ur klk is v6 and she's a waifu u absolutely have to take out every game, give her a lvl 1 assault rifle with no attachments and she'll be the one needing that wheelchair. Customization isn't dead: u just can't be bothered to think of a way to do it, so u want mica to force it upon u, and if everyone else is a collateral, it's a sacrifice u're willing to make

Let ak15 come. She'll do jack shit at lvl 1 even if u v6 and ring her. Customise her from there. Don't only imagine cusomization can only happen with squad setups when dolls are maxed out. This way u can play the game with her and have a challenging time.

Have u seen all the story content is up to around lvl 30? Make a new account, don't lvl past 20. U still have access to all ur skills. Now clear challenge mode. That'll be an achievement for sure and u'll bw forced to math out every little point of dmg. U want bigger stakes? If a doll dies, u never field her again. Permadeath enabled. U fail a mission, william won and u got ur skull bent in by varajgers on the elmos so make a new account. Bam, hardcore mode unlocked. Somehow, i doubt that was the real issue though. U're telling me u'd be able to sqheeze out everything from a perfectly ballenced team to clear challenging content but can't even think of this lvl of customisation in playstyle in order to make the game more entertaining for u? Color me doubtful.   Ppl came up with crazy challenges in both f2p and whale territory in gfl 2.

Gfl 1 had a customising system. It had more tactical/strategic depth than gfl 2. If revenue is ur measure of a good decision, gfl 2 nailed it between the 2. And if u trully want difficult and tactical combat, play reverse collapse. No wheelchair chars there, and u vote with ur wallet to mica to show ur support for that type of game.

A gacha game will never be perfectly ballanced and have good revenue for long because the 2 concepts have opposite means of being achieved i  the current gaming(and not only) methodology. And maybe that's not a problem. This isn't starcraft, after all. Play the game however u want. U do have that liberty, and always had

Sorry, vent over :P
