>>31476893It was always based on usage.
>>31476823I gotta agree. Gen V introduced too much. Abilities like Sheer Force, Prankster, Magic Bounce along with their wide distro (HA or not) which was very tough to counter. Furthermore, abilities like Speed Boost, Magic Guard, Shadow Tag and Mold Breaker became available to non-shitmon.
Baton Pass got too OP with Shell Smash, Quiver Dance, Bounce Espeon and Scolipede, whereas before only Ninjask could pass well, and it couldn't do much more outside passing unlike Scoli/Espeon.
They went too far in Gen 5, and went even further in Gen 6. Gen 7 tried to tone it down (Tapu/UB not withstanding) but that didn't magically undo the royal powercreep the previous two gens introduced.
