Build for patch 3.0 - Solidstate

This Wednesday patch 3.0.2 is coming to WoW, bringing with it many changes, not the least to the talent trees. As there will be about a month between patch 3.0 and WotLK, I need a good spec for Solidstate that:

1. Will be useful to me at level 70 for about 1 month.
2. Can be used for mainly soloing and raiding/instances
3. Is fun.

I've already decided I will go full Frost once WotLK arrives as it is simply the best leveling spec possible. Therefore I have decided to go Fire once 3.0 comes, specifically this 0/53/8 spec.

I went with fire because I want to try something different before I respec to "boring-old Frost". I want it to be good, or at least viable, damage in raids. I also from looking at Arcane just don't see a good raiding spec there at 70 since the AB nerf.

My choices for talent points started with the requirement to have the extra 3% spell hit chance from Elmental Precision, meaning I had to spend 8 points in the Frost tree. Everything else was put in the Fire tree, mostly I tried to take talents that would increase my crit chance and spell damage. Regarding the spells I didn't take:

1. I didn't take Improved Fire Blast because I just don't see Fire Blast as a viable part of my spell rotation.
2. Burning Determination is a clear PvP spell so that's out. Although it would have come in handy in some specific fights, I just couldn't spare the points.
   
3. Impact - pure leveling/soloing/grinding spell, not really useful for my purposes.
4. Molten Shields - silly spell :)
5. Blazing Speed - PvP.
6. Fiery Payback - I was confused about this spell description. Reduced damage is always nice to have but hardly essential for a mage. Increasing the CD on Pyroblast while decreasing the cast time? That's good for what exactly? It looks to me like the developer here couldn't make up his mind...
7. Firestarter - nice to have but I don't see Flamestrike as being all that useful even as an instant cast. Especially if you're close enough to be using Dragon's Breath or Blast Wave on the mobs.
8. Playing with Fire, Hot Streak - I had 1 point left to use up. PwF looked like the more solid upgrade to damage. HS the more fun talent. I went with fun :)
   

It's really too bad about the Arcane tree, I really liked being an Arcane mage with "uber" damage. Ah well, back I guess to doing mediocre damage, at least untill WotLK is out and we all start leveling...
