Call me a newbie shaman then but here what i do in a typical RSS grp:
[step1] Buff the grp, grp wunshi, haste(if no chanter)stamina, sense, agility, diaku, regem, billy(incase no one has run5), and tribunal. After rebuffing done im down to about 30% mana. We take a quick break and i regen my mana(pained momory, canni5, mod rods(i always grab one from a mge in GH).
[step2] I load my grp spell set which conists of this, and it is in this order: 1)Pained Memory 2) Ice age 3) Spiritual Serenity 4) malos 5) Yoppa's Mending 6) Curse of Sisslak 7) Breath of Wunshi

Balance of discord 9) Blood of Yopaa.
[step3] Inc Mob--First thing i do is slow it asap with discord.
[step4] When slow lands, drop malos on it.
[step5] Click TA
[step6] Curse of Sisslak
[step7] Breath of Wunshi, Pained Memory
[step8] Blood of Yopaa
[step9] I click my EP greaves and get pox of bertoxx to stick.
Thats a typical RSS grp for me, when i have the extra mana ill drop in an ice age, but i like to dot more than nuke simply because imo i do more damage. usually by this time my last dot lands(clicky pants) the mob is at 40%, and Pained memory comes back up i click that, my final resulting mana is 70-78% provided i started with 100% mana, i then click canni 5, and shoot back up to full(or 90-95%) I do not leopard, simply because its boring and i dont have the mana to keep up with a full grp and dot, i hate it when i drop below 50% mana, rarely do i EVER go below 50m, only happens when cleric goes poof(dies) and i have to heal. WHen im bored of doing the above steps ill do this:
[step1] slow
[step2]malos
[step3] click ta
[step4] leopard myself
[step5] bandolier my hammer of hours and whack the mob(i have a 125life sapp aug in my hammer of hours)
During my melee time, ill click pained memory, drop in a curse, and my pox of bertox pants, and an ice age or 2, depending on length of fight. after fight ill canni back up to full cuz all that usually brings me down to 80% mana.
dont get me wrong fellow shammies, if my grp dps is uber horrid ill Leopard anyone and anything that melees and lay off on dots and maybe throw in an ice age or 2.
Thats just me, no im not the best, sure i might be doing it wrong, but its how i play and how i enjoy playing so shizam! lol
