Which abilities you wished was better?

IMO, Run Away should also let you switch out to another Pokemon instead of just fleeing. For example, Pachirisu is your current Pokemon in battle. Suddenly, your opponent switches for a Pokemon with Shadow Tag or Arena Trap. The Run Away ability could let you switch to a different Pokemon scott-free.

Slow Start should provide more defence stats while the attack/speed is halved! It would make Regigigas NOT a complete pile of doodoo.

Pickup should allow a Pokémon to pick up an item it lost to Knock Off at the end of the turn.

Anticipation should give away a move that can Knock Out the Pokémon that has it in one hit.

This way that ability can actually be a bit useful.

Illusion: Give moves a 10% chance to miss. Granted, that would probably be too broken.

My poor birds need Keen Eye to provide an accuracy buff unless they want to be really generous and let Big Pecks block Sword of Ruin.

Gen 1 Stench. It does NOTHING in battle. At least in later gens it lowers accuracy.
