While what you say is not wrong, its not effective either. Using W for escape limits your engage potential as it's pretty easy to predict a big ult coming out of Wukong if he just runs up and E's to someone. His Q armor break doesn't really make a whole ton of sense, maxing it second so for 10% to 30% armor debuff, the armor break doesn't do a lot where you use it the most, in lane, because later in team fights you can only hit one person with it, and while it is a great burst tool the damage amp is actually pretty insignificant, maybe about 110% damage output after using it, plus more often than not your going to use it after E AA and hence only it and maybe an extra AA get the buff. AOE slam would benefit him much more. Ult is very strong, I agree, however after the first few ticks it becomes slightly underwhelming, as he becomes vulnerable and his damage output is gated, as he is in a state of channeling. Bruiser builds like
actually are fine, but it's wasting potential of either going full AD and making the most of your strong multipliers but risk dying, or going tank which makes you durable, but you do little damage besides initial burst and you don't have the CC to justify it. Another thing I want to clarify is that using W to escape is wasted potential except to do trades in lane, to negate retaliation. You cant W during your ultimate, and using it after you will probably end up dead anyhow from the chaos of a team fight, using it to make a sneaky engage which the enemy is not prepared for is much much better.
