Ensign,
We use cudgels, sickles and peasant gear because we are either:
1) Bored with the game so we look at the other hundreds of underused weapons and armor because we don't want to be longsword spam #420
2) Trying to make massive profit from cheap gear for a gen
3) Having immense fun using such gear
4) Want to destroy the egos of people who think they're tough shit
While it is true that it may be harder on average to maintain a decent score using sickles, daggers or any other 'useless' weapon you still see great men like FrugFrug or JesusChrist top the scoreboards with their dilithium rocks of justice and staves. You must remember that many human societies value and cherish individuality. This can appear in many aspects of such a society, from hipsters to indie games or movies, even some mainstream brands use individuality as the message of their marketing campaign. Anyone can pick up a longsword and start spamming their way to the top, but where is the fun in that? We as a species thrive on challenge. Challenge and curiosity. We do not want to be reduced into crunching numbers for some immortal machine and turned into a hivemind (Although that can be argued with the way our society is progressing.).
Calling out peasants on not using a 'decent' weapon and because of that not contributing to the team is rather dumb. Is there some sort of CRPG e-sports league that emerged while I was on an away mission? What exactly is there to complain about? Your team loses so you don't get an x5 so you don't level as fast. Boohoo. Now, if this was Strategus I would understand since there would be something at stake rather than just your petty ego, K/D ratio or multiplier but if this is the extent of your reasoning then you can kindly get out of my office and back in your comms chair where you are stationed.
tl;dr stop fucking sperging on people's perception of fun in c-rpg
