Downfall of Arcanine
Everyone who saw the Attackers tier list knows that Arcky got tier 3, but why?
He's still the best fire attacker, still tears everything that dont resist it, so why the low ranking? Even Blastoise is on a higher rank and it became worthless with it's nerf and vaporeon boost.
Since he's still great overall attacker and best grass destroyer he deserves a higher rank.

I think GP takes into account the best defenders people are using so with so many Vaps, Rhydons you now see, water/grass typing is much more useful as attackers since I have seen an insane small number of grass types in gyms since...Most grass types also got nerfed a bit...
Lapras is there, but is still more rare and sits lower in a gym now so probably due to the Rhydon effect...
I honestly don't agree with even having an attacking tier list, when attacking, you should mostly look at the highest DPS per type chart and judge YOUR local metagame for yourself, when you defend sure, having a chart that tells you which pokemon are the best at holding a spot in a gym is very useful, but when attacking you can just pick whatever it's best to defeat any given pokemon of any given type and be fine. Now... the point here might be that with the rise of Water and Rock type pokemon as defenders, there are many more pokemon that resist Arcanine's attack, so his rating as an attacker was punished as a result.
I guess it depends of the Tier definition.
My definitions:
Tier 1: Best Attacking Pokemon against a wide range of Pokemon. (Snorlax, Vaporeon, Dragonite)
Tier 1.5: Best Attacking Pokemon against a narrow range of Pokemon. (Rhydon, Lapras).
Tier 2: Second choice Pokemon when you do not have the preferred Tier 1/Tier1.5 equivalent.
Tier 3: Third choice Pokemon when you do not have the Tier 2 equivalent.
Since Arcanine is the second best Pokemon against Exeggcutor and grass Pokemons after the rare Dragonite and Snorlax, it meets my Tier 2 definition. (or Tier 2.5 if grass Pokemon are rare in your metagame).
On the other hand, Exeggcutor, Gyarados, and Waterish Omastar are worst than Vaporeon for every fight. They should also be Tier 2. (And, compared to Arcanine, rarely useful Tier 2 since everybody has a Vaporeon but not everybody has a good Dragonite)
Charizard is actually the best fire type now since it is double resistant to the grass types you'd typically use a fire type on. There is no need to use Arcanine against Lapras now since Jolteon's stats were buffed (you're just trading ice resistance for super effective attacks).
The only time Arcanine shines now is if you're facing an Exeggutor with Confusion+Psychic, which is a pretty narrow niche.
