Brainstorm to GO, part 3

'Sup there, coming back to register a few ideas I got while driving home.
It's mostly related to gym battling, due to the fact that there should be some sort of reward for stronger or more dedicated players. I'm against the idea of allowing those to dominate the game, but a game has to be rewarding too, that balance is complicated.
The first possibility is assigning the position of Gym Leader. The first golden badge bearer to put a pokémon into a gym becomes its leader (I thought about making lvl 30+ a requirement, but I ain't sure about that part). The leader gets to be fought last and gets a huge bonus, something like doubling the monster's CP. Yeah, the Gym Leader is the Gym Leader, right? It's still beatable especially if you got a party taking down the gym, but it adds a little bit of a challenge.
Another rewarding aspect of a gym could be, getting stardust for taking it down. I thought about really small amounts of dust, like 10 for every fight won, or maybe one or two hundred after taking the gym down. It's few, but it's something. Also, for every attacking pokémon that gets defeated during the entire gym battle (from the first to the last defender), the trainers defending could get some stardust. Small amounts, but with a high daily limit, so that people have some motivation into defending lots of gyms with the strongest 'mons they got.
As for the legendary raids, I'm quite concerned about the long-term consequences of them as it stands today. Sure, it's fun, it's desperating, it's frantic, and expensive in some cases. But they don't seem to hold well if you look some months ahead. I agree that they should be damn hard to catch, it's nerve-wracking when you get a bad luck streak, but it's part of the game. The thing is, it seems a bit off getting armies of legendary birds, if you look into the game's lore. I'd suggest having the players only being able to bestow one of each, as in, you got an Articuno, wanna participate in an Articuno raid? Well, let that one go and try a new one. That makes them relatively unique, but brings the problem of raid scarcity over the table. Once people get their high IV birds, they won't help others in raids, and then those late to the party get squashed. Also, they should be allowed to defend gyms, but maybe with a limit of only one legendary per gym.
Ah, maybe raids could give some other recovery items aside from Revives... Potions are welcome...
