The first I heard about "Tiers" was the first time I condemned them and I never really stopped doing so.
I was never blissfully ignorant enough to assume that every game had perfect balance. Some characters are, indeed, superior, but anyone who honestly believed that such balance could be quantified and ordered by a finite number of people of finite skill was condemned in my eyes.
I have become a lot more accepting in my time here but the underlying fact remains. The fact that Melee can keep going and keep having new stars shows that it's bigger than any of us. To think you can reduce everything to percentages is a little absurd and to believe that you can do so accurately is utterly ridiculous.
But, if you're wanting to talk about character strengths, I had very little opinion back then. Kirby was obviously the best character but not for any strength reasons, simply because he had the most visually and mechanically distinct attacks. He was wacky and he had personality and I could actually play as him.
The only characters I had a power level opinion on were Roy, clearly a bad Marth, Ganondorf, a horrendously slow falcon and thus one of the worst, and the Links, down there with him because they were lacking in virtually every area (only 2 jumps, predictable recovery move, lots of endlag on grab, slow item throwing and mediocre damage). Oh and Ice Climbers, their 2 on 1 ability made them broken.
Besides Link, I'd say I did ok.
