Yea there are actually many factors to include when measuring/comparing gacha, such as pulls, pity available ? (if yes, random ssr / random onrate ssr / can pick, how long it takes to reach), number of total chars, powercreep, overall ssr rate and rateup, are there dupes (if yes, what do they do / how important are they?) etc etc
The vocal gacha-praisers in this sub seem to only look at "here 10000 pulls for you" so u'll see skewed perception about gacha "generous = good"
And in genshin case it's matter of perspective, like for casual f2p/low spenders they accept the fact that :
Wont have every new 5*
At most said 5* will be c0 (unless lucky to get dupe in same multi)
But then the haters will always point stuffs like ceilings are way too high (esp c6r5) and f2ps (or low spenders, or even dolphins) wont have maxed etc etc
Which funnily enough theres a thread (got removed by mod I think) where supposed whale(s) talking about c6 in genshin is "useless" bc it makes things way too ez
And in regards to gbf, ppl conveniently forget primals and limiteds and whatnot exist --- it's still good gacha for f2p but it's not like f2p can literally "minmax everything possible ala whales" either cmiiw
