This made me think. How would everything change, if pokemon's secondary type only had half the effect it normally has on elemental match-ups?
Like Ledian's flying type would only count as half-weakness and half resistance, so Rock type attacks would do 3x damage and Grass type attacks would do 0,33x damage?
Also STAB would be halved so Ledian's Flying type attacks would only get 25% bonus. Would this balance things or would it just make everything worse?
