If RIOT is going to replace the Rift Herald

One thought I had upon hearing that RIOT was going to change or remove the Rift Herald, was that it could open the door for another elemental dragon to spawn in the Baron pit. This dragon would spawn at the same time as regular drake, 2:30, but it would roll its own element separately; that is to say, you could (and usually would) have dragons of different elements bringing in more variety, and causing teams to choose which is more important. As soon as one of the dragons is slain, its kindred fellow sensing the death of one of its kind will roar, knocking back champions (similarly to when they are first attacked) and then fly away off the map.

The goal with this change would be to not only bring in more varieties of elemental dragons, but also to allow dragons to be contested in multiple ways as only the first one to go down counts.  Additionally, since only one dragon per spawn can be killed, and there is a solid chance that the dragons are different, it would add an element of strategic choice.  "Which buff is better for us, now, as a team?" begins to become an actual question, as RIOT seemed to originally envision teams would have to wrestle with when they released the current incarnation of dragons.

Further, I can't help but think that topside having potentially the "better" dragon spawn might alleviate some of the current metas focus on botlane and shift it, at least conditionally, back to top lane.  I wouldn't be surprised even if duo lanes might go mid to exercise control over both spawn points, and then top and bot would be long solo lanes that both could roam to mid, influence their respective dragon pit or happily lane and push-- not that this would necessarily happen, but it might be a possibility.
