I think that sort of list format is ideal for this game (or at the very least it's much better than what we're currently doing). For the reasons I stated in my last post here. Does anyone disagree?
The major issue I foresee lies with the characters who fluctuate between high and top tier in peoples' list. These are traditionally characters like Jigglypuff, Peach, Ice Climbers, and Captain Falcon. On occasion, Marth and Sheik are in the mix too. I also imagine some of the fringe characters like Mewtwo, Bowser, and Yoshi will likely have a high variance of opinion and likely have a lot of conflict attached to their grouping.
Having said that, I still think the MVC2 style grouping makes way more sense for this game than an exact ordering that has to be changed super duper frequently and potentially go through an extensive overhaul. An overhaul that will demand some manner of an official, agreed-upon process for it to be taken seriously at all or accepted by anyone (which we don't really have right now since there isn't an MBR anymore [though frankly nobody ever listened to us anyway] and MIOM hasn't touched the tier list). I feel that even in the instances where there isn't any sort of dominant or stabilized opinion on where a character should be ranked, it's much easier to move Mewtwo from "Tier Group 4" to "Tier Group 3" than it would be to place him exactly within either.
edit:
Basically, I agree with what Bones0 posted earlier on this one. Which I've put below.
edit 2:
The only other things I feel we might miss out on by doing the list in a grouped but no-order fashion is that we don't state who "The best character" is or who "The worst character is". I actually feel that these are drawbacks because the tier list is (on paper) a resource for newer players and knowing who the best character is has value in theory. But whenever someone asks, we never f
ucking agree on that anyway. And going forward, I don't think we will agree in the future either. I strongly suspect the people who bemoan the existence of Fox and rue the day someone jumped out of his shine... will continue to rank him on top, regardless of whether or not he's doing well in tournament. The boys who cried, "Jigglypuff!" back in 2010 will likely still jump on whatever the current fad is. I'll still probably say, "IMO Falco."
So ultimately I don't think we lose anything.
As a side note, I think it might be more useful to keep a more formal, official record of how many of each character was in the top 16 of each 100+ entrant tournament in the last 6 months and keep that list on the front page of Melee Discussion in its own thread. This way, we have a record of who's popular and I have this suspicion that when someone asks who the best character is, they're on occasion (but not always) asking who they need to look out for. In which case another list for representation (which does not necessarily have any bearing on the grouping list BTW) would be useful. And even if they're not asking that, it's still a good resource to have.
And for the people asking for who the best character is because they literally want to know who the best character is... well, they're gonna get different answers in this community depending on who they ask because that's how we roll. And it's not our fault. IMO our game literally seems to resist settling down. Which is incidentally a big part of why it's such a good game.
