Provoke - Is it necessary?

[abzoluut]

I can't think of another class that HAS to bring a cross class skill to function. Many are nice (swift cast, etc) but WAR might be the only that is basically required to bring one.

I'd say swiftcast would be pretty mandatory for SMN/SCH/WHM. Can't find a reason why not to swiftcast fester gaols on Titan EX, or swiftcast raise during encounters with bosses or.. Should I really go on? xD
