Dragon should spawn in alternate locations throughout the game
Why does this make sense? Because in games where one team's bot lane is just incompetent that team can still effectively contest objectives.
If dragon 1 spawns bot and your bot is losing, it's hard to get that dragon if you're not going for an attack speed jungler. But if your top lane is doing well, then you have a higher chance of securing the dragon if the second dragon were to spawn in the scuttle pit.
I'm not sure how the map would look, but I think if there was a minor re-design that allowed the dragon to spawn in multiple locations it would add a lot more strategy to the game, and it would also prevent one team from getting all or most of the dragons just because one team's bot lane ints all game.
