a) "Tanks are dead", specifically "health tanks are very dead"...that's the reason Mundo and Maokai are never seen on Pro play (or Nunu, some Elise builds and tanky supports like Thresh and Braum)

b) A tough champion with plenty of cc is useless...because you know, locking down a target or a whole team for 2-3 seconds so your lategame ADC can kill them safely and you win the game is not important (because you are not doing big damage)

c) A couple months ago this was still considered by many a bruisher meta, and ADCs were nigh useless...

Thing is bruishers and assassins can kind of work alone, while tanks, mages, supports and marksmen need some teamwork. But teamwork beats solo play in most cases, it is just more difficult to see in soloQ
