Drake buffs unrealistic?

Hello, I haven't played the new patch yet, but reading patch notes I'm a bit confused as to how drake buffs work. They only stack if you kill the same element, i.e. you can kill infernal drake 3 times for a total 24% ap/ad buff (insane, right?)... But you can have 3 elements in a single game and elder drake comes in at 35 minutes. Let's say you get infernal, mountain, cloud, infernal, mountain, cloud, infernal. 7 drakes in you'll see your first 3rd stack of drake.. That means 6 minutes * 6 drake respawns = 36 minutes. It's not even physically possible to achieve that. Is this just another piece of RNG added to the game? What am I missing here?
