Yea, if you're W/E don't concentrate on fire magic, you're gonna have alot of people get pissed at you...
You should instead grab tanking skills (via. guild wiki, link in post above) and use elementalist skills to help "buff"(strenghten) your normal skills. Such as:
[skill]conjure flame[/skill]
another "classic" combination is the hamstorm Warrior (not sure how effective this is anymore):
[skill]Hamstring[/skill]
to cripple
and...
[skill]fire storm[/skill]
to bring em down, kinda funny.
For terminology, there is a wikipedia guide:
http://en.wikipedia.org/wiki/MMORPG_terms_and_acronyms
(that took FOREVER to find...
bookmarked)
For a guide for player by player, that'd be guildwiki. Link is in above post.
Dancing is /dance
A good chunk of the emotes should have come with your game
Hope this helps..
