A few things to help Tiki out on her pala tanking mission.
Mouseover taunt macros:
-- Great for Ret to start combat as well (solo only ofc)
#showtooltip Hand of Reckoning
/cast [target=mouseover, harm][target=target, harm] Hand of Reckoning
/startattack
-- Mouseover the person with aggro or click on them or click a mob that is attacking them
showtooltip Righteous Defense
/cast [target=mouseover, help][target=target, help][target=targettarget, help][target=focus, help] Righteous Defense
-- Great for killing runners, really handy in Vanilla Dungeons
#showtooltip Hammer of Wrath
/cast [target=mouseover, harm][target=target, harm] Hammer of Wrath
-- Mouseover spell macro, BoP, Cleanse, Salve, heals, etc still needed while tanking
#showtooltip
/cast [target=mouseover, help][target=target, help][target=player] Hand of Protection
There are 2 addons you should get to help make things smoother:
Pala Power - Displays your current buffs (including RF, seal and Aura) plus it makes it easier to buff others and select their buff. Something EVERY pala should have.
Tidy Plates, Threat Plates - Lets you configure the HP bars over mobs. Mine displays tiny bars on mobs I have aggro on but huge bars on mobs I dont. This makes it easy to select them for attacks or use a mouseover skill, great in aoe situations.
Both are available on www.curse.com
As I said earlier when levelling I found Ret to be better for tanking until level 50ish, Prot goes oom very fast.
