Less Dragons that Mean More (also first one spawns later)?

As the title says, fewer dragons but have them matter more. Maybe they could have a different type of non-perpetual buff? Also maybe have them have a rotating location with later initial dragon and baron spawns. I am just brainstorming atm, but the Herald drops the minion, maybe Dragon gives a couple RNG op versions of the Elixirs (or not RNG and they correlate with whatever dragon spawns) w/ a smaller team stat buff?
