I hope they buff some abilities this Gen, I think it's a bit likely since they've been rather focused on making so many new ones this Gen already.
Run Away should allow the Pokemon to escape from things like trap moves and abilities (Shadow Tag, Arena Trap).
Keen Eye should boost accuracy like Compoundeyes.
Pick Up could remove entry hazards when sent into battle (not my idea but how amazing is this?).
Flare Boost should give immunity from the Burn Damage tbh.
Illuminate could drop the opponent's accuracy one stage upon entry (or maybe not since this could be annoying af).
Light Metal could double Speed.
They did it with some abilities in Gen V (Storm Drain, Sturdy), so they can do it again.
Y'all are of course free to disagree.
