Right now my feats planned are:

1 Least dragonmark of healing
1 Maximise
3 Empower
5 Mental Toughness
6 Spell Focus: Evocation
9 Lesser Dragonmark of Healing
10 Heighten
12 Greater Dragonmark of Healing
15 Spell Penetration
15 Spell focus: Enchantment
18 Toughness
20 Greater Spell Focus: Enchantment

I'm currently level 10, and have all the feats up to level 10. I'm really really loving the SLAs my archmage has while retaining metas and dragonmarks. I can't stand warforged so don't even bring that up.

So as I am loving my evocation focus, and about to hit level 12, is GSF: Evocation worth it for infinate chain missiles and cyconic blast at later levels? Basically SP free casting- only spending SP really on buffs and CC. (Stuff before 20 exists)

I could take it at 12, take GDM at 15, and delay SF: Enchant. What do you think?

First character, currently the highest I have. I was told to switch out evocation focus for conjuration for epics, but I don't know, I really am loving the SLAs.
