Why make a random objective (Dragons)

Why add a random element to the game? lets say your a kill based team and the enemy is a poke. and a poke based dragon is up. this adds a situation to the game in which if you lose the enemy gains more but if you kill them then you have to take the poke based dragon just to deny it from the enemy and maybe thats not the best call idk. but there is no reason that the champions you pick should differ in power in the game based of random elements. This will determine some games just because of a random thing in it and will give another reason for why people are in bronze.

i understand that riot wants to make dragon more interesting and i agree its a step in the right direction.

why not make it so the first dragon that spawns is the fire dragon and the 2nd is the earth dragon and so on and so on. idk what im thinking or what they should do maybe im the only one that thinks randomness shouldnt be in the game but im speaking out if you agree plz upvote if you disagree downvote if you want thank you for reading glhf in the future.
