I agree that this particular case leads to confusion, and should be made clearer. Even moreso because this happens early in the game, and not everyone has massive MMORPG experience. I have seen people who played FF14 as their first MMORPG, and abbreviations such as these can be complex when inexperienced, when absolutely everything in the game is new to them. Having to learn things they never heard before, such as "aggro" and "enmity" and a whole plethora of technical terms, it can be overwhelming.

On a sidenote, I recall people talking about "levelling their bot" and taking me ages to figure out they meant botanist (BTN). Now that's a rather silly one. x_x
