Hello

Working on my destinies on my first life sorc and have been wondering for a while if I should focus on spell penetration or not.

My setup at the moment (human sorc, lvl 23)
Extend
Empower
Maximize
Heighten
Toughness
SF/GSF/ESF Evocation
Spell penetration

So I'm thinking I either drop Extend for Greater Spell Pen and then take Epic Spell Pen at 24. Or I drop Spell Pen and take something else (not decided yet) and maybe grab Epic toughness at 24.

It would also free up some destiny points to not have to spec into spell pen.

So what do you guys think? Is spell pen needed on a sorc? My necro/enchant DC is not that impressive but Energy drain can handle that if I have enough spell pen.
