Kurona asked some questions about HGSS. Being one of the people who originally wrote it I figured I would answer some questions:
A few things I noted while going through the tier list thread in regards to HGSS' current list on the website:-
-First is that quite a few Pokémon are judged on their obtainability from the Pokéwalker; notably Kangaskhan, Doduo and Elekid. Would we still do this in an eventual updated HGSS list?
I honestly hated adding Pokewalker stuff (I was one of the people who was against it at the time) and I honestly would rather have not added them in. I don't remember Fireburn's stance, and I will not speak for my old friend on that either. My personal opinion - I would rather just have two tier lists - one with HGSS as normal, then a tier list strictly for PokeWalker Pokemon and nothing more. Requiring anything external outside of trading.
-The Red Gyarados doesn't seem to be ranked separately, which probably does make sense and I'm just dumb but it still felt odd especially when Gyarados' ranking is specifically marked out with Magikarp.
That may have been from with whoever took it over or maybe just me blanking out. Anyway, the premise on this one was you had a trade-off - get a Magikarp (or Gyarados) earlier, or take the Red one and stick with it. Red is usually a bit better from my experience to be honest, but in general rule is unless the Pokemon has a weird condition behind it (trade evolution) or is some obscene gift they should just be tiered the same and just note which is the preferred option in the description.
-And most glaring of all especially when compared to the GSC list, Kanto doesn't seem to be considered at all and certain Pokémon are decidedly untiered because they're only available in Kanto; notably Houndour and Suicune. Should this be the case in an updated list?
Suicune probably would receive a rank still since it's caught at a tolerable level and the like, but some like Houndour would probably go to an Unranked or E (whichever is preferred, for consistency).
I have expressed interest in re-vamping HGSS in #ingame in Smogon the other day, and would actually fully commit to it and more Tier Policy - but the sacrifice would be dropping SM and ORAS tier lists, but to be fair these are two tier lists I really don't care about to run anymore and would rather focus on GSC / HGSS.
