windfury level 32 you should check out that site it lists all the spells and level you can get them.

my team is at 26 and only use the abilities i need to. my mages and lock pretty much just spam one spell each and i have no problems (full clear rfc, sfk and doing bfd tonight probably). we'll have to step up the complexity eventually but at low levels you can get by with a simple setup. dont know about the warrior strat though i havent really played one in a while.

as for questing i dont know im pretty much instance grinding to learn the tricks of my team.
