Terminology. Why does it bug me and others?

[Gramul]

People say pally instead of PLD?
...that's stupid. That sounds, looks, and functions on a heightened tier of stupidity.

Its not even shorter.

For real? Is this a real complaint? Seriously?

Terminology is actually pretty important. Being able to clearly communicate with your party is essential for smooth play.
Talking like a baby when referring to classes and abilities sort of throws a wrench in the cogs.
