Comparing AK gacha with endfield.
Endfield gacha seems horrible compared to AK.
In AK on limited you got a 70% chance to get one of the rate up so 35% each, in endfield its 50/50, it should be 60/40 or even 70/30.
The 6* in AK is 2%.
Soft pity starts at 50 in AK +2% per pull which makes your 99th pull a gurantee. In endfield its 65 +5% per pull and 80 gurantee.
So here is some probability of both games.
In 50 pulls you are 64% Likely to obtain a 6* in arknights. In endfield its 33%.
In endfield its 40% likely to obtain the 6* in 65 pulls. Arknights reaches 40% likelihood within 26 pulls.
You need 75 pulls in endfield to be above Arknights gacha rate with 55.8% vs 54% soft pity.
It is much less likely to get ops in endfield and this is simply not good and it's even worse for whales.
The major difference is that its a 50/50 with 1 gurantee vs 70/30 with 2 gurantees who each are 35%.
I don't factor in Weapon banner due to you essentially being able to obtain it over the character banner and some character signature weapon are skippable in other gachas as well.
