Dragons should Spawn like Scuttle Crab, randomly between Baron Pit and Dragon Pit.

This is literally all Riot has to do to change around how impact full each lane is. Make Dragons spawn randomly at the start, and then have it rotate between each pit until Dragon Soul Is Claimed. After Dragon Soul is claimed Baron Spawns in his pit, maybe he could be buffed to have as much (or more) health than Elder Dragon I don't know, but after you slay him you gain the Baron Buff, which is literally the current elder buff.

Extend the Top lane alcove and make Rift Herald Spawn up their if you really want her too, or just remove her from the game, it's up to you.

All in all this would fix the top lane/bot lane importance issue that we currently have, allow for a bit more team play and make Baron an actual important objective that helps you close out games instead of something you get as an after thought or out of habit after acing the enemy team.

Elder Drake is more important than Baron is right now, even though Baron is supposed to be this games Roshan/boss camp.
