Are you NA? It is worth trying to kick if you can block while kicking. You will miss a lot (most) when you are first starting out, and it will get you killed if they are really poorly positioned kicks, but it gets better. Also, make sure you aren't so focused on kicking that you forget to block.
It may be worth noting that if you use a knockdown weapon, you can hit them on the ground, then kick and get another free hit in. So one knockdown gives you three hits (the one that knocked them down, the hit while they are on the ground, and the one where they are stunned from the kick).
