What if rift herald was just another dragon?
Rift herald is useless and needs to be reworked in a way which makes going top lane desirable for a jungler.
Idea 1: The first 2 dragons (no more since baron will spawn) now have a 50/50 chance to spawn in either top pit or bot pit. The dragons are functionally the same as now. If the baron spawns and kicks a dragon out of the pit, it resets, gets mad and flies away to the bot lane pit.
Idea 2: Both pits spawn a dragon at the same time and each have their own timer. The top pit dragon will get deleted like rift herald if baron spawns. Dragon buffs are lowered to accommodate the possibility of 2 more dragons to be killed
