Actually I am glad someone posted this since I was totally owned in Ramps because of not healing so much, kind of hard to stop DPSing to heal at least for me it is at this point. How about the following:

/castsequence [harm,nodead] Lightning Bolt,Lightning Bolt,Lightning Bolt,
/castsequence [target=TankName] ,,Lesser Healing Wave,
/castsequence [harm,nodead] Lightning Bolt,Lightning Bolt,Lightning Bolt,
/castsequence [target=TankName] ,,Lesser Healing Wave,

Might be out of room there at the end, but in essence it would be 3 LB's, Lesser Heal, 3 LB's, Lesser Heal, and then back to LB's. I would assume this would work but I have not tried it. But then again I guess it would screw stuff up since you cant really throw in CL since it would probably reset the castsequence so it would screw up your healing at one point.
