Yup. And Ezio's WR BB is i18, that's why it doesn't work.. To punish his 11K, Ezio's 6B works well, specially the BE version. But against the 33B at tip, I think Ezio can only use his CE.I checked the guide and all his lows are unsafe for the most part (most are -16).
I don't think 1BBB is a good option. If he enters Prep on block (except for 66(B)), he is at -2. His Prep Bb(BE) [i11] would intercept your 1BBB, I suppose (unless 1BBB has TC). Besides, if he enters on block, his standard action should be Prep 4, which would either evade, or aGI your 1BBB.Also, if he ever attempts to transition into PREP from near anything (except 66B), you can interrupt anything he does with 1BBB and get a combo. If he does do 66B ~ PREP, he has frame advantage and will beat you, unless you CE him because the CE's invincibility frames will allow you to interrupt him for free 100+ damage (since CE does 90 dmg + Counter Hit + Clean hit opportunity [A])
I'd suggest 66B (though it is still vulnerable to Prep4, it's less vulnerable than 1BBB). You can also try iWR A, though it would be vulnerable to Prep K. A+B's TC is no good, because the second hit of Prep BB or Prep AB can catch Ezio mid-air.
And he enters Prep on hit, I'd suggest ducking and getting up if your read the kick coming.
Ezio is very vulnerable to Prep, with the Exception of his CE, I suppose.
This one is good after a Guard Burst and it's a very consistent wall combo, which is a rare think for Ezio.I Only know of one good wall combo 44k, 1bbb, 4kw!, 4kw!, a+b, CE give me some better ones
44K 1BBB 4K 1K 6b(BE) - 109 dmg (around it, there is a Clean Hit possibility)
It causes pretty much the same damage as A+B CE, but less half a meter.
It's not a great wall combo, considering it's specific beginning (44K CH) and that it uses meter, but it's very consistent. And you don't even need to be very close to the wall, because the first for hits can drive your opponent quite a long way.
