Vayne:

Q max is definitely a viable path, but if you aren't doing specifically well, W max is really good too. because its not only 8% of their total HP, but it also has a flat amount that scales. It really depends on what you build first. if you go BT then take Q, if you take PD/BotrK then you max W.

Riven:

maxing Q, then W, then E is teh path you should always take. unlike what Ozuar says, Riven's W actually does good damage when leveled and the CDR is extremely nice too. Riven is meant to burst people down, not to rely on a 2.5 sec duration shield to drag out the fight.

Katarina:

W max is good. Q is possible, but W is better.

Lulu:

Q max is much better. W's range is rather short hence using it for damage is almost never possible. Q max is more consisent damage wise and its got good CC too.
