When people hear terms they aren't familiar with or that didn't derive from the first MMO they played they automatically think that it came from WoW. Pretty much all those terms I can coin from pre-WoW MMOs, but the fact of the matter is that WoW brought in a huge influx of players into the MMO environment so this is where a good portion of the MMO player base picked up these terms.
I think the only solution is to abolish all that is different and use the same term for everything, right? because having multiple terms to describe one thing is never found in any language, especially not in english. We should just go a step further and go full south park and shun anyone who doesn't..
