You seriously have too much denial within you. Corrin's side smash is incredibly hard to sweetspot due to its range, their down smash is weak unless you sweetspot it, though it's easier to land than the side smash, it's still by no means easy when you have an opponent with a working controller, and up smash, you'd really have to be in denial to think that this is a good move, sure, it's sort of strong when sweetspotted, but you're rarely going to do so unless your opponent is foolish enough to challenge it. Additionally, you have yet to provide any combos that aren't 2-4 forward airs, and you deny Falcon's spot on the tier list, the bias is very clear here. None of you have provided substantial proof that Corrin is even above Luigi, whereas I can prove that they're not.
first of all, when talking about kill power, i wasnt talking about his smashes...i rarely ever use corrin's smashes to kill. his kill moves are mainly upair (which is easy to set up) and side-b (also fairly easy to set up), additionally counter(even though counter shouldnt be considered too much, since...well...it is a counter.) oh and back air... secondly, you telling us, 2-4 forward airs is the only thing corrin has, clearly shows me that you barely play the character at all...this is incredibly...ignorant.
true-combos corrins has: DFS to full hop DL tipper, DFS to pin and kick,DFS to Fsmash, weak hit of DL kick into aerials, Fair to DFS in the air, DFS into footstool into dair into pin( even though pin isnt true), dtilit to utilit, dtilt to upair, dtilt to reverse grab, landing nair to anything (preferebly footstool) into more aerials, nair into bair, DFS to dash attack, falling fair to pin at very low percents, DFS to uair, DFS to bite, falling fair to footstool to nair to bair( or alternatively use another fair in the air and then footstool) those are just the true ones (depending on percent and character, if the opponent is above 80% the DFS combos are very easy to do and deadly with tipper DL)
now, give me cloud's true combos. very curious.
then, im not denying falcon's spot by any means. he is about where he should be and a good character. he just lacks a good mixup game. all he has is his speed. if you cut him off coming to you, it is very very difficult for falcon, hence why he isnt at the top of the tier list if he is so fast, does have so good combos, good recovery, is heavy and kills fast. sounds like a top contender but wait...yea. i like falcon very much and im not biased lol. i wish marth was good to main him again, but he just isnt. corrin is just a very complete character that has no true weakness aside from very mediocre recovery, but still, not bad. what makes corrin so good is his mixup game and the tools he has for each situation. he isnt just straightforward. and i think you dont really realize, what makes corrin such a solid character. great neutral, great mixups, decent combo game, has easy kill confirms at higher percent, decent kill throw, mobility is far from slow but also far from captain falcon mobility but fast enough for how corrin is played. corrin threatens space so well, that opponents HAVE to respect it due to the lance and overall range, causing opponents to shield even if you arent that close which opens up grab opportunities. corrins frame trapping is also very strong. he is good at playing footsies. but corrin is also relatively easy to gimp and can have problems against characters like fox who can camp with a projectile and otherwise go in on you if you become impatient. corrin is probably at his worst at CQC. and so far only fox can do that pretty reliably, since he can also force camping. you can brick wall the rest. oh and his frame data is actually better than average, just sayin'.
and now for the last point...im really curious for your proof that luigi is above corrin. really.
ill compare both for you and then you can comment if you want.
luigi is slower than corrin with terrible air mobility. luigi doesnt have good kill setups, whereas corrin has. luigi only has reliably low percent combos, corrin has combos at any %, corrin's neutral is much better. corrin plays footsies better. both arent the best at approaching, which, in corrin's case, is somehow mitigated by how fast side-b comes out and the threating of space i meantioned before. luigi just loses against some top tiers/high high tiers. corrin isnt clearly disadvanteged as far as i can tell, except against fox. being able to set up into one of your kill move is a huge deal, and corrin is able to do that. luigi edgeguards a little bit better i would say, though. at least against non linear recovery, that you can just side b with corrin.
really, im not denying anything, corrin is a very solid and complete character, and that completeness makes him good. just think about side-b for that matter. which character has a move that is: a movement tool, a spacing tool, a combo tool, a killing tool AND a recovery tool( depending on stage) all in once that comes out incredibly fast.
for some reason you are just seeking negatives without providing actual evidence and falls argument (only 2-4 fair combos for example) without taking the positives into account that absolutely outshine the negatives and help to play around them. and that is important at the end of the day, cause each and every character does have weaknesses (even sheik, yea)
there is absolutely no reason for luigi being above corrin.
but everyone has their own opinion i guess, and if you think corrin is c-d or even e tier, well then, thats ok.
