I feel like tanks should be extreme nuisances, never incredible 1 vs 1 threats.
I feel like a tank should mostly be there to be a meat shield and to bring lots of cc. I feel like now most tanks are ridiculously powerful, able to 1 vs 3 at times. When I play Jax and I finish BOTR and Triforce on him, I'm still usually losing a 1 vs 1 against a Maokai, that just sounds so wrong to me (over 100 games on Jax with a 65 percent win rate in ranked, so I know how to play him). I think they should lose their mega 1 vs 1 potential by lowering their base damage on spells, but allowing them to split push for TP plays by giving them bonus damage to minions to help waveclear.
