Name annoying things that people do on certain Classes/Jobs.

[Chukkaque]

Sometimes tanks spin them to avoid frontal AoE, other times to position it to not hurt his/her party members. If the tank is just dancing around for no apparent reason I suspect s/he's just bored and needs a cookie.

This can be avoided by simply side stepping out of the AoE and as soon as the indicator vanishes moving right back to the position.
