I don't want to go too in-depth in to this argument because I don't want to come over as a rude, hardheaded person because I 100% respect your opinion and can see where you are coming from.
I think there are many more things to go over on the Viability rankings, one of which I will go which is why I'm going to keep it short but here are some things that Zard has over Pyroar:
- It's a fighting check. even though it's highly pressured by SR, it can still come in on most Hariyama and Hitmonchan sets, especially the Physical wisp-set, which doesn't have an item and makes it an even easier switch-in to Knock Off. Sure, its a shaky check, but it can switch in to most things while Pyroar can't as it will easily get boned by a Mach Punch / CC.
- It has recovery in Roost and isn't limited to max. 5x switching in when SR are on the field as it can find an opportunity to Roost off most damage dealt to it when switching in to things that it resists. Zard also has actual defensive utility, which Pyroar absolutely doesn't.
Yeah I have to agree with you here. the surprise factor isn't really a big deal, even though people normally don't really pay attention to items in the team preview. It's a good way to scout though, although I think I saw someone post something about special zard w/o an item and Acrobatics > Air Slash, which looked really promising to me. The surprise-factor is fairly small with Zard, but the same thing can be said for Pyroar. there are 3 main moves and then a toss-up between WoW, Overheat, Flame Charge, Wild Charge, or Taunt. I'd say the former ones are the most used and I haven't seen Wild Charge being used a lot at all, as it's more of a counterteam-thing.
with that being said I definitely can see where you are coming from but I think Zard is right where it belongs at the higher end of A+.

ok now I also wanted to touch on this thing as it has been sitting at A+ for way too long and I think it's good enough to be S-Rank.
A+ -> S
Steelix is pretty much a staple on almost all Balance-teams, because it is so good at what it's supposed to do. It checks so many things and there is almost no reason not to consider using it as a Rocker on stall-balance teams, and even on offensive teams that need a solid pivot + rocker.
Steelix is easily comparable to the other bulky grounds in the tier but the Steel-typing does it really well and here are some things Steelix has over Rhydon, Piloswine or Torterra.
- it can switch-in and beat Musharna without too much trouble. most Musharna's run Psyshock (atleast in my experience) and even after a couple of CMs, Steelix has no trouble dealing with it as Heavy Slam + Toxic is way too much damage for Mushy to handle.
- not losing to Kangaspikes as badly as the other rockers. Steelix' immunity to Toxic Spikes, resistance to normal, combined with taking pitiful damage from Earthquake/DrainPunch.
- not having an exploitable (4x) weakness which makes it hard to lure in. Rhydon can be lured and beaten by Swellow's HP Grass while it is supposed to be a counter to Swellow. Steelix, on the other hand, is weak to Heat Wave, but 1. doesn't take that much from it and 2. will see it coming and is always wary of it.
- it will almost always get up SR, because of Sturdy. Xatu (common) and Taunt-users (not-so-common) are the only thing that stop it from getting up SR, and with the amount of spinners we have, those rocks are there to annoy your opponents team for the most of the game. most defoggers really hate Toxic too (Pelipper, Mantine) which most Steelix' run too.
One of the few reasons I can see for Steelix not to go S-Rank is that Xatu beats it, which is pretty huge. Regular defensive Xatu doesn't get 2HKOd by Heavy Slam and always prevents Rocks. This is a really valid argument against it going S-Rank but honestly Xatu isn't a staple on most teams and has to be wary of not getting Pursuit-trapped in order to keep SR off the field for as long as possible.
There hasn't been that much discussion on Steelix, but I think there should be more posts and thoughts about it since ever since it has joined the tier it's been popular as shit, and there's a good reason for that.
