This is what you are searching for.

Nope nope nope. I have played GSC for a while and I can tell you that it is simply not the case.

There's a very interesting read by borat that can be found here :

which led to a generation where defensive Pokemon ruled the metagame. Games would last hundreds of turns, and no one had any fun.

Actually, gen II can be an aggressive metagame when a skilled player use a offensive team (BDLax, Marowak, Growth Vaporeon, Explosion users...)

If they were to get rid of Abilities, they'd nerf Regigigas / Slaking.

And more importantly that would be removing one of the most interesting aspects of the game, so I highly doubt they'd remove Abilities anytime soon.

Male Combee is so awesome that it is banned from Little Cup

You're too slooooow !

PP: 10

Priority: +3

Prevents the target from using any priority damaging moves for three turns.

That would be useful against several threats but not broken as the opponent can anticipate it and choose U-Turn or another move that turn. It would allow some Pokémon that lose their match-up due to the priority move to actually win it against an opposing Scizor / Aegislash / Azumarill...
