the real point is that it would be too busted in game balancing if the S+ devil fruit was even partially immune to a A or S tier devil fruit. The S+ tier is already better in the material and the AoE rules.
I think if we, for example, make Ice immune to Snow then it would be a slippery slope to make a bunch of things immune to a bunch of things.
Possibly we can give it +1 resistance to snow and do things like that based on the DF chart oda gave us in the SBS.
Problem is when you do it like that, it leads to completely absurd situations in the actual RP.
Cause now, if there's no immunity, you're forcing the ICE MAN to go and RP being cold, which is just absurd lol. Plus here on TB, we have many more stat points than we did on WURP, so everyone has DF and MA and Haki, so it's not like you're completely relying on your DF.
I just don't know how you expect a Mera person to RP getting burned by something that's less hot than themselves, or a Hie person to get frozen by something that's less cold than themselves. Makes no sense.
Also, it feels kinda weird that you're taking away something that's canon and you're justifying it by saying that that fruit would give too many things, of which some of them are custom things. Then take away the custom bonuses not the canon ones.
Nowhere in the manga does it say consuming a fruit increases your strength, speed, vitality, etc.. So I dunno why they do here. Take those boosts away, instead of an actual canon one.
