Tanks and Bruisers need higher level 1 defenses
Let's be honest, you buffed the hell out of ADC base defenses and now they are basically on par with Tanks and Bruisers. Meanwhile ADCs get crazy high level 1 offensive stats.
Now I am not really talking about buffing someone like Lee Sin to have high level 1 base survivability
but there a lot of Tanks and Bruisers that need at least another 100 HP at level 1 (WITHOUT HURTING THEIR SCALING) and probably another 3~5 armor
