WMMLP vs WMMMP Endgame and key maps

[Tazeon]

I play WMMLS

control perspective:
singel target is for mage and wl 1 button. wl castsequence curse and then shadow bolt spam. mage spam firebolt.
aoe i have 3 buttons, wl always cast hellfire (in some instances I use rain of fire), mages flamestrike, blastwave, arcane explosion

I know I don't use the full damage potential from a WL and a 3rd Mage (even more if you use fire, which is the better instance spec) would lead to much more dps. aoe would also be a lot easier because of the high burst fire aoe damage (flamestrike, blastwave, arcane explosion)

but the WL has so many other big advantages / utilitys
SS - even more useful if you have a priest healer, (shaman have ankh)
healthstones
bloodpact - if you dont play Soul Link
PORT - saves so much time

x) if you run an instance very often and get a lot of loot or have to repair (DME)
x) to reset an instance its also helpful, to port out of instance, log out with others, reset and port back - faster then inviting another 6th charakter
x) if you want to travel anywhere in the world, you travel with 3 charakters and can do other task with the other charakters (I have 5 lev20 wl spread in the world to port me to the many places, but even then I must sometimes travel)
x) during leveling process

Port is the big advantage why I prefer WL.
