Hi!
So I tried all three mage specs in new patch with rotations, gemming and reforging as suggested here or at icy veins and this is what i got:
Fire: Nice touch with new "heating up" system, nice rotation, dont need combustion helper anymore, althrough its still viable. Can use FFB again without any downgrade (used glyph slot, but what are the options?). AOE damage comes from flamestrike and then blizzard, if you want to get closer then dragon breath and arcane explosion are options. I was using living bomb, that is preety much unchanged. However rotation and whole system seems to be boring.
Frost: Lots and losts of things to cast. Frostbolt is really only a filler, brain freeze and fingers of frost are popping up all the time. AOE is same like fire. I was using frost bomb and didnt like it because of cast time and short time to blow then. Maybe thats me, but I wasnt able to use frost bomb like it needs to be used, all rotation is kinda crazy and superfast.
Arcane: Changed a lot. Rotation is a real rotation finally. Fast but not fast as frost. I was using nether tempest and liked it a lot. Great AOE damage from nether tempest casted on every mob (no max. number of targets yet) so random damage from it is on everybody and arcane explosion that generated charges itself. I was using real rotation with mana gems and evocation only on bosses, but thats fun too, there is no thick line on burning vs conservation phase like at last datadisc.
So funwise: 1. Arcane 2. Frost 3. Fire.
Whats your opinion?
Also, sorry for my english.
