Idea for Dragons?

So... we want Dragons to be contestable, and meaningful, with buffs that are good for certain comps etc. Enter the elemental dragons. But how, I ask, is RNG contributing? Thing is, RNG can actually say screw your team comp. 3 Wind drakes, forget your poke comp which favors water and fire drakes just as a single example.

Not only that, but the Dragons have a clear tier of importance, even when compared to other objectives:

Fire Drake Turret Mountain Drake Water Drake ANYTHING ELSE Wind Drake

I have a suggestion for Drake with a limited RNG (not even a necessary RNG, but it doesnt really break anything).

• Each elemental Drake only spawns once. Once all Drakes have been taken, Elder Drakes will spawn for the remainder of the game.

-Fire Drake: Increase team AD based on level (1% per 2 levels) and increase damage to monsters and minions by 10%. -Ocean Drake: Increase team AP based on level (1% per 2 levels) and increase resource regeneration by 10%. -Mountain Drake: Increase Bonus Armor based on level (1% per 2 levels) and increase HP regen by 10%. Wind Drake: Increase Bonus Magic Resist based on level (1% per 2 levels) and Increase out of combat Move Speed by 10%.

-Elder Drake: Transfer 1 Elemental Drake buff from Enemy Team to your Team. If you have all 4 Elemental Drake buffs, Double Their bonuses and gain a DoT burn on attacks for 2 minutes. Buffs Transfer in order of how they were gotten.

Obviously, these are rough ideas, but you get the idea.

1. No more Random Drake combos. The Drakes are now something you can plan for/around.
2. Strategic importance depends on comps. All AD team? Fire Drake or Mountain Drake become very important that game. Heavy AP? Ocean and Wind. Playing with lots of tanks? Mountain and Wind. No tanks? Fire and Ocean.
3. Drake remains relevant whole game, because Elder Drake simply moves Drake buffs around until you have all 4 buffs. This means teams that are behind have the opportunity to try and slim the lead by contesting and controlling the Drake, shifting power back towards themselves and away from their opponents.
4. Even if you keep the RNG to mix it up, you still will have 1 of each Elemental Drake before Elder. Even if the Drake that you specifically want doesn't spawn first, it still priority to get it to move on to the next.

Any thoughts on this? Can I get a RIOTer's opinion? anything?
