Thoughts:

Now we get a chance to look at what Inscriptions will give to Mages in WotLK, and they all look pretty good at first glance. There are some which give a boost in PvE and some good for PvP and some are just good all around.

For PvE, a plus +5% bonus to Frostbolt and Fireball at the cost of losing the slowing effect and dot. For Frost Mages this is a big plus in raiding where bosses aren’t slowable by Frost Spells anyways. An extra 20% Mana regen from Mage Armor to help out the Arcane Mages, and an extra 2% Spell Crit on Molten Armor for Frost and Fire Mages. Cooldown reduction on Water Elemental by 30%, and Improved Scorch stacking 5 at once are both good too. Polymorph removing dots! No more broken sheeps in raids due to mis-dotting Priests and Warlocks.

For PvP, an extra 5 yard range on Ice Lance gives it a 41 yard range with talents. Ice Armor gives an extra 20% armor. Icy Veins removes slowing effects on you will also help a lot in PvP.

Then there are Glyphs that are just good all around. Extra mana return on Mana Gems, immunity to curses after a decurse, and of course Polymorph: Penguin, can’t forget that one!
