If this is a solo build, surely they're on about a different build than the one I viewed on pvxwiki. This is the one I viewed - http://www.pvxwiki.com/wiki/Build:E/Me_Terra_Tank
Also, this build does damage to nearby foes for 10 secs via [skill]sandstorm[/skill] which I'm assuming would cause aggro around me to break & mess everything up for the rest of the party, so surely this can't be the terra tank build they're on about

I was thinking that possibly they were just confusing "terra tank" with "obsidian tank" shown here - http://www.pvxwiki.com/wiki/Build:E/D_FoW_Obsidian_Tank
^^ Obsi tank makes a lot more sense than the terra tank shown above for tanking UW.
Anyway, it seems the majority of people going into UW these days are Ursans & seeing as I only have Proph, Factions & Nightfall I can't join their party as I'm not Ursan. The only way for me to join their party would be if I was a terra tank, which is why I'm asking these questions.
I'd appreciate all the help I could get, thanks a lot.
