I feel like
Lucario should get the "Guts" Ability (if only to have a pseudo-reference towards Lucario's Aura mechanic of the Super Smash Bros. series, in which
his strength increases with the amount of damage that he's sustained).. It would've worked nicely being situated as a Hidden Ability; maybe being placed in a future quaternary Ability slot will suffice..?
-------------------
As for weather-based Abilities, I initially felt that Drought and Drizzle should remain exclusive to Groudon and Kyogre (Rayquaza also having Air Lock as an exclusive Ability would've worked, but then comes the more commonly-available Cloud Nine Ability to dampen things).. I was somewhat bummed when Ninetales and Politoed received Drought and Drizzle respectively (meaning that Groudon and Kyogre both lacked signature Moves
and signature Abilities, lessening their legendary status a bit in my eyes), but I got over it when their Primal forms gave them buffed versions of Drought and Drizzle, respectively.
In any case, I still felt that if they
had to go to non-legendary Pokemon, Drought and Drizzle would have been better suited on other Pokemon - Vulpix and Ninetales can't even learn Sunny Day by leveling up as of the release of
Pokemon OmegaRuby/AlphaSapphire (yet strangely, Delphox, also inspired by
kitsune, can learn Sunny Day by leveling up), and Politoed doesn't seem any more distinct than the various other Pokemon that can learn Rain Dance by leveling up in some form.
Ulgamoth (Volcarona) and Masquerain seem more fitting for having Drought and Drizzle as Hidden Abilities in my opinion, as some of their Pokedex entries specifically allude to both sunlight and rainfall, respectively (Ulgamoth's fires are said to serve as a substitute for natural sunlight, and Masquerain's wings can signify impending rainfall - then again, there is the snag of Masquerain having difficulty flying when it rains >.<)..
Articuno should really have Snow Warning as a secondary/Hidden Ability by now.. I tend to perceive "passive weather manipulation" as a trait more befitting of legendary Pokemon. In Articuno's case, it was the first legendary Ice-type Pokemon and has Pokedex entries just littered with references to snowfall. Not to mention that it seems the most fitting and imposing candidate for a powerful "100% Blizzard under hailstorm" attack combination. I don't see why the Snow Warning Ability should be limited to non-legendaries like Abomasnow/Mega Abomasnow and Aurorus, especially when those two Pokemon could really benefit from other Abilities
(like Flash Fire Abomasnow, amirite?)
As for Sand Stream, now that I think about it, I would not have pegged Tyranitar and Hippowdo
wn as the sole users... I'm hoping that
Flygon one day receives Sand Stream as a second/Hidden Ability, due to its numerous Pokedex entries mentioning it being the "Desert Spirit", being "
always enveloped by a Sandstorm when flying", and its wing flapping sounding like singing (the sole thing heard within one of the Sandstorms that Flygon's wings whips up).

This floats but doesn't have Levitate:
While this doesn't float but has Levitate:
Whyyyyyyyyy
where is that one picture
Manami Amamiya of Gakuen Utopia Manabi Straight! (in Episode 4) and Jackie Chan to the rescue, yo. But yeah, Magnet Rise and/or Air Balloon for Magnezone just doesn't cut it.. >_>
I wish Castform also gained combat stats upon transformation into other formes with it's ability.
Other than that, I do agree with Zekrom that Magnemite and evos probably should at least have levitate as a HA because well...they are obviously floating and ground is their biggest weakness.
Yeah; Castform the little guy needs all the help that it can get; it has such a nice gimmicky Ability..
Cacnea, Cacturne, and Maractus should have Rough Skin because they're cacti.
Frost Rotom should have Refrigerate because it's a refrigerator.
That would be a perfect Ability for Cacturne due to the lack of a proper secondary Ability. As for Maractus, I guess a quaternary/4th Ability slot will have to suffice someday.. Frost-Forme Rotom with the Refrigerate Ability makes sense, although by that token, I feel like the other Rotom forms would need additional/Hidden Abilities as well for "equality/balance"
(except Wash-Forme Rotom; screw that piece of junk >.<) ..Aerilate for Fan-Forme Rotom, I guess?
-------------
For some reason, although somewhat unnecessary, I've envisioned Groudon getting Sand Stream as a Hidden Ability, in my opinion - mainly due to the earthy affiliation...this is one case in which I wouldn't mind the imbalance - although you could give Kyogre Snow Warning for the watery affiliation, it would have to be likely re-typed to Water/Ice to take proper advantage of hailstorms, which means normal Groudon might have to be re-typed Ground/Fire for "counterparting type duality" purposes...although Primal Kyogre would make more sense for Water/Ice typing since Primal Groudon is typed as Ground/Fire, although (Primal) Kyogre is more associated with rainfall via the Primordial Sea Ability.. >_> @_@
