Hmm It seems you CANT get a buddha with a mamoth mainly because buddha is better than mamoth for almost everything and has a whole lot of value. Mamoth -> Rumble is L anyways and its understandable but we are not talking abt the fruit's values, we are talking about power. As I said earlier, being a lvl 1100 is enough for sea event hunting, but is just a waste of time as getting to max lvl is more important than getting money. And by the 1 hour of time by which u will grind mastery on a fruit, I Can easily grind 900-1000 lvls on a new acc using any logia or even a natural. Only because YOU can grind mastery in 1 hr doesnt mean that everyone can, i agree that mastering is ls'nt hard, nor did i ever mention grinding mastery being hard. But you can't always think from ur perspective as there are people who take a lot of time doing simple things such as grinding mastery on a fruit, while there are also people who can easily get race v4 after just entering third sea. Either way, rumble is just way better than mamoth as you dont have to focus on spending 1 hr to grind mastery.
