here is an example:
/castsequence reset=5 Strenght of Earth Totem, Grace of Air Totem, Healing Stream Totem, Flametongue Totem
this should work although it may need you to also put (Rank #) after spell but i can not recall.
anyhow you can shift click spell and put them into macros so it really is not a problem, you just put in /castsequence reset=# (5 works good here) and then shift click your spells in putting coma and space in between each spell.
