LoL is fairy balanced, although admittedly some champions become literally impossible to stop if they have a great early game (Jax, Xin and Jarvan come to mind), but even then, a tank will always be invaluable to the team, and it's usually tanks that control the map for the entire team. All Amumus I've seen make sure to ward all buffs and take them just in time, and remember to use a vision ward on Nashor, giving their team the luxury of safer jungling without as many worries. Ofc they know how to properly initiate too
