To be quite honest, while I'm not gonna say anything regarding Goodra's rank placement, I feel the responses to that post are being unfair to Goodra as a whole. I personally am not a huge fan of the AV set and I honestly think that's the worst way to use Goodra. Its Choice sets however are actually pretty neat. I've used Goodra quite a bit lately out of my own curiosity, and while it does have some issues, I have found that it really does check quite a few things in the tier (it has the resistances to really use its great Special Defense well), and then it can do quite a bit of damage once it switches into something. The Banded set can switch into Seed Flares from Shaymin for free, and sponge shit like Fire Blast and Volt Switch coming from stuff like Chandelure, Heliolisk, etc. If you do wind up switching into that stuff, Goodra can fire a pretty powerful attack for super effective damage given its incredibly good offensive movepool and coverage, or just outright fire a strong Outrage or Draco Meteor (depending on whether you use Band or Specs). The Band set isn't fodder for Suicune because you have the luxury of Power Whip, which hits Suicune pretty damn hard, and it hits other Bulky Water-types in the tier hard too (and we have a handful of them), while Iron Tail allows it to smash Florges and Whimsicott. The Specs set can also enjoy the super effective coverage of Fire Blast and Sludge Bomb, and in general, the Choice Sets can find their uses on some teams as something that comfortably switches into many of our special attackers (and surprisingly sponges hits really well) and then retaliate with its great coverage to hit well, fairly hard. The AV set is the worst Goodra set in my opinion, but if you do end up using it, it does have some merit in having a pretty damn good matchup against offense, since it's really hard to take down in a single blow (it survives Draco Meteor from Hydreigon!!!) and then it can retaliate decently well with its coverage, which is enough against offense. Sap Sipper is also pretty cool since it absorbs Grass moves and Sleep Powder (ahem Venomoth). Considering these circumstances, Goodra is pretty capable, since what it does have, its stupid special bulk, and its great movepool, allow it to switch into something pretty comfortably then dish out quite a bit of damage. The constant statement of saying "Goodra is so easy to wear down and it hates status" could really be applied to things like Mega Blastoise too (obviously Mega Blastoise is a better Pokemon, but I'm just saying that thing about Goodra could be said about some other Pokemon too).
I'm not really arguing for anything regarding Goodra's rank placement, I'm simply saying you guys aren't really giving it enough credit. Goodra is by no means some super amazing Pokemon, and obviously Salamence and Hydreigon are way better Pokemon, but I feel it should at least be looked at fairly. Goodra in terms of individual performance is a pretty decent Pokemon and if there weren't so many Dragons in the tier it would be much better. That's really the only big issue with it. Other Dragons exist. That's the real reason it probably is sitting in the lower ends of the rankings. Things like Salamence and Hydreigon are so damn good in this metagame that finding a slot for Goodra becomes...somewhat difficult, despite being objectively decent. That's really all there is to it.
Oh and regarding Fletchinder. It's fine in B-. Its does have some terrifyingly strong priority, but that doesn't change that it really needs a lot of support to work well. It literally has only one good aspect about it, and that is having priority Acrobatics. That's a niche, but Fletchinder needs a lot of support to perform. You need effective hazard removal, or else it's gonna struggle to get any setup opportunities since SR cuts its HP in half. It's so damn frail that finding a setup opportunity becomes difficult, especially since it's weak to Scald and that will probably instantly kill it. It's also kind of weak without a boost, so you kind of need to set up. It's a decent Pokemon, with a good niche and is very capable of sweeping once it sets up, and its STAB is good too considering it does hit some stuff super effectively. However, something as weak and frail as Fletch and support reliant shouldn't really go above B-, despite being worthy of that rank.
Geez I had too much to say. Also btw Haxorus comes before Heliolisk in ABC order, someone please change that, it's kind of bothering me. Unless people want Haxorus to drop from B+, but I doubt that's the case anyways.
