Rift Herald is a Game Changer
Might question me on this but grabbing rift herald might win you some games. The reason why is towers are more important than ever and every tower you get increases the potential of your minions, Rift Herald gives minions pushing power and gives you Damage and move speed allowing for quick escapes or the ability to turn fights around while the pushing advantage of the minions might snag you a tower or 2. If your lucky you might destroy a inhibitor tower allowing you to backdoor it getting super minions which in turn can distract them while you grab baron giving you even more pushing power. Point is it can spiral into a bigger lead probably even more than dragon since it gives you a bigger impact for the moment you grab it, although if you don't do anything with it its wasted while dragon its always there so it cant be wasted. Also as a funny thing when I do get the buff it usually tends to be when im a support and I urge my jungler to grab it since he was going sated or we couldnt contest dragon but he ends up giving me the buff, in fact when I do it with top laners same thing and I get the buff, even though I feel a top laner is better with it, idk maybe supports can do some more good with it but not sure
