Encumbrance doesn't effect your sidestepping speed. Is sidestepping while heavily encumbered an exploit?

'Crabwalking' while heavily encumbered, or under any other sort of movement-slowing penalty, is definitely an exploit.

That being said, Crabs are Nature's wonderfruit.

This is, without a doubt, my favorite and most amusing exploit.

Crabs are neither amusing nor fruit. Zoidberg takes offense.

But they are exploits. <_>
