For instance, Twain spells "after" like "aafte", but in my accent I would probably spell it "afdr".
Twain has also run in to the problem that spoken English has far more vowels then written English does. He uses "ai" in both "minds"/"maindz" and "replace"/"riplais", but presumably they represent different sounds.
Presumably OP's system has the same problems with the dialects of Chinese, now that I think about it. Although I know very little about Chinese unfortunately (only what I know now from a few seconds of googling).

I personally enjoyed it and never had much trouble figuring it out, but know people who found it unpleasant and incomprehensible.
Of course, the degree to which the complexity is disdained varies depending on who you ask: Japanese saw fit to reuse mostly as-is, Hangul chose to replace it wholesale, and so on. Simplfied Chinese is somewhere in-between, not replacing wholesale but simplifying characters often to the point of bastardization.
My favorite is the simplification of 龍 (dragon) - in Simplified Chinese, they took the right hand side and derived 龙; in Japanese Shinjitai, they took the left hand side and obtained 竜.
"For example, in Year 1 that useless letter c would be dropped to be replased either by k or s, and likewise x would no longer be part of the alphabet. The only kase in which c would be retained would be the ch formation, which will be dealt with later.
Year 2 might reform w spelling, so that which and one would take the same konsonant, wile Year 3 might well abolish y replasing it with i and Iear 4 might fiks the g/j anomali wonse and for all.
Jenerally, then, the improvement would kontinue iear bai iear with Iear 5 doing awai with useless double konsonants, and Iears 6-12 or so modifaiing vowlz and the rimeining voist and unvoist konsonants.
