Are you asking how good a Link with no custom moves would be in the custom meta? Somewhat lower than where Link would be with customs.
This is more what I'm wondering, yes. Comparing Palu to Link is more of a visual representation.
However, the question isn't whether customs Link is better than vanilla Link, it's where customs Link and vanilla Link both place on the same tier list. "Somewhat lower than" isn't that tangible an answer, since another part of the question is
who actually fits between them?
How many custom characters are better than vanilla Link?
How many vanilla characters are better than custom Link?
How many slots higher than vanilla Link is custom Palutena, if there were a singular list covering everything?
That's a good thing, by the way, because if we treated each custom set as a different character my 3 character tier list would suddenly look something similar to Sheik, Sheik, Sheik, Sheik, Pikachu, Pikachu, Sheik, Rosalina, Rosalina, Rosalina, Sheik, Rosalina, Sheik, Rosalina, Sheik...
EDIT: I had a big paragraph already here but shot myself in the foot with a tangent and confusing the tagent with a second tangent, so I've rewritten it.
Best way to avoid a redundant tier list like that is to better compress the available custom characters, for brevity. If four Sheiks all share the top place above Pikachu, does there really need to be four of them? Does all four custom sets supply such broad variety that a player would become severely upset that they can't play as a specific setup?
My overarching conclusion, in regards to my previous 'named sets' helper, is to compress a lot of the existing EVO customs for
brevity, variety and
synergy.
There's very little tangible purpose in having, in Smash 4's unfortunately limited options, ten redundant sets when they could be covered by two or three summarized versions. Having so many sets just to fill the slots is confusing for players who have no idea which is which, useless for players who need to scroll through all of them, and pointless when more than half of them will never
actually be used.
Using Pit's lovely EVO custom spread as an example (2111, 3111, 1112, 2112, 3112, 1113, 2113, 3113), is there
really eight different styles of play between them? Doesn't everyone hate Dark Pit's crappy arrow? Why would they use it
on Pit instead? Is there really such a severe difference between the two available barriers that the Pit subforum drew a line in the sand whether you're for or against one of them?
All of Pit's customs as-is could probably be compressed into just two or three, instead of eight. As for which, that's up to which works best from a perspective of
synergy with the rest of Pit's moveset. That is a better manner of customs discussion than just, "We need 8-to-10 custom sets, pronto!"
And by compressing customs into a smaller number of sets, we make more specific tier lists more possible, and give the customs-inconclusive crowd a better ground to jump on if they feel like giving it a shot.
Moreover, by focusing on the synergy and brevity itself, we make room for more experimental sets that are presently off of EVO's roster and potentially unexplored. Nobody uses Luigi's fiery jump punch since the knockback is piss-poor, and nobody uses clothesline tornado because it's slow and unwieldy. But what if the two synergized well together, and clothesline setup into a scenario where fiery jump's improved range let it land consistently (or vice versa with Fiery Jump's poor knockback)? Probably not in this example, but we don't know how many sets have been overlooked wherein a subtle synergy might exist.
Everyone's so engrossed in the strongest moves, that from an outside perspective the game becomes boring. It becomes about the strongest moves themselves, and not about how the weaker ones could set up more impressive combos and kill confirms. And that's... not really 'customs' so much as it is 'artificially buffing'.
Is there a difference or reason to use a broad variety of custom Donkey Kongs when, ultimately, the central move is Kong Cyclone? Would these other moves work better in a set excluding Kong Cyclone, instead? I wish I knew
that, instead of just 'customs DK is high tier'.
