Getting tower as early as possible is not always a good thing
Just played a game where our entire team was behind on towers, I lost the first turret on top, bot lost the first turret on bot, with only one tower in mid taken before our own fell as well.
But in the end, it didn't really matter, we made some great plays, evened the KDA before taking the lead, took advantage of the enemies baron throw, pushed, and won. In fact, taking our towers too soon actually hurt their own team, when it made them lose potential CS.
So despite what people are saying, Rift Herald is not as bad as people claim.
