I just hit 80 over the weekend on my team, and actually had a question about ToW.

For single shaman DPS, its recommended to glyph ToW for extra SP.

For a team of four shaman, do you:
A) drop four ToWs and get the buffs
B) drop 3 ToWs & Flametongue (gimping one shaman to help everyone else)
C) drop one ToW & different totems for everyone else
D) drop four ToWs, get the buff, then drop three different totems until the buff runs out - I don't know if this works, but when I recall my ToWs I still have the buff icon (it may be doing nothing SP-wise)
