Ooo, yeah, that'd do it.
Don't take any of what I'm saying as a criticism by the way. I have my own design philosophy where warlocks are involved, so what I'm saying must be taken more as sort of, "This is what I'd do," talk...
That said...I think you're blowing too many feats on more invocations. Remember that no matter how many invocations you have, you can only USE one per turn (blast shape and essence notwithstanding) unless you have Quicken Spell Like Ability.
I also think some of your invocation choices are...not what I'd call optimal, though I recognize some are to fulfill prereqs. Here's a breakdown on invocation picks I would suggest reconsidering.
Least
Devil Sight
- This is a terrible, terrible power. See the Unseen is the same level, gives you See Invisible AND Darkvision 60...which is functionally nearly identical. Yes, Devil sight pierces magic darkness...but since magic darkness is only a 20% miss chance now...who cares?
Lesser 3 (+3)
Ignore the Pyre (Dragon Magic p. 82)
Relentless Dispelling (Comp Mage p. 124)
Voidsense
- Ignore the Pyre isn't actually too bad, but you can get better with a Ring of Universal Elemental Resistance for a mere 200-odd grand, and a ring slot. Relentless Dispelling is all but useless at epic levels against anything remotely close to your CR. Voidsense isn't useless, but if you have See the Unseen (see above) then you won't likely need it.
Greater 3
Eldritch Line (Dragon Magic p. 82) or Caustic Mire (Comp Mage p. 98) or Repelling Blast
- Line areas are the worst, in my opinion. Cones and spreads are much more useful. Repelling Blast is sometimes nice for "caster" style warlocks, but less so for a melee, I'd think. Caustic Mire just seems too weak to me for a Greater invocation slot at these levels.
Dark 3 (+1)
Caster's Lament (Comp Mage p. 123)
Eldritch Doom
- You'd probably be better off with Devour Magic than Caster's Lament. I suppose it depends on if the GM rules Break Enchantment can de-petrify, which is otherwise the only thing Greater Dispel can't do better than it. Eldritch Doom is...I may reconsider this. For a blaster, it's awful, but if you routinely get in close anyway...that might be okay.
Let me think summore...
