Here are the patch notes: (Retrieved from http://forums.f13.net/index.php?topic=16113.0)
Not sure exactly what this means for mages, but looks like they are only changing arcane. Seems to be a slight buff to arcane missiles (through glyphs) and a change to Arcane Power that doesn't seem all too big, more just decreasing arcane's burst potential. Same thing with the AP/PoM GCD, this doesn't affect raiding mages too much but definately hurts PvP Arcane. Also, If i remember Arcane Flows correctly, it used to reduce Evocate cooldown, and with the removal of that it means mana issues for arcane who poorly manage mana. If this is all geniune, the only nerf arcane raiding mages are recieving is less evocate time and arcane blast glyph (arcane blast glyph was changed in 3.0.8a but was bugged for arcane missiles), so overall its more a slight buff for arcane short term damage, but may cause problems for arcane's sustainability. Only time will tell. Though I must say that most mages might be trading in Arcane Power or Arcane Blast glyphs for mana gem... 40% 2 set Frostfire +40% glyph = 180% Mana Gems... and that mana is critical for fights. For shorter fights like patchwerk, Arcane Power, Arcane Blast, Arcane Missiles glyph setup will probably be optimal but will cause pain on long fights like Sapphiron and Kel'thuzad. But only time will tell, and maybe the changes will actually be different.Druid (Skills List / Talent + Glyph Calc.)

But on a positive note: Sartharion Shadow Fissure changes are gladly welcomed. Now no more reason to be stepping on them anymore (Or no more things for me to blame :( )
but seriously, nothing is worse then being on Sarth + 3d with all drakes still alive and being stuck between a fire wall and a shadow fissure!
