Hello. I don't think this will be able to help, but this is my rotation. XD
Grind Single Targets (I don't really do this much..)
Fire Bomb-Lightning Bomb-Fire Bomb
Snow Storm-H3ll Fire-Snow Storm-Snow Storm/Lightning Web
[SS mobs, HF when they're rooted, start casting SS again right in front of you]
Dungeon small group pulls in dungeons
Snow Storm to infinity~
[I find that it kills faster, or at least you can't utilize 12sec. duration of HF to its potential, especially when there are other DPS in party...HF when there are beefmobs mixed in..]
Dungeon Single-Target (with lotta HP.)
...same as Dungeon Bosses formula.
(Resistance Collapse > Winter Chill x3 > H3ll Fire > Magic Boost > Fire Bomb + Maintain Winter Chill) I'vent tried this.. o_o I don't really count on RC&EG, never LV'ed 'em up, I always thought they'd be more useful in PvP... >_<
Mine is: [Winter Chill x3 - Lightning Bolt - Fire Bomb - Lightning Bolt - Fire Bomb - Winter Chill - (Lightning Bolt+Fire Bomb)x2
[I usually count on stun and crits from this two spells (FB&LB), and could use both two times each before I really need to recast WC. Also helps on MP conservation if there's no Illu for me. +Extreme Magic if need to kill fast..)
Heard Extreme Magic is more for PVP? [Yes, I don't doubt that. Cast Speed + a lil' more power ftw. XD]
Is Resistance Collapse in your rotation against bosses? Pretty sure it is? [Not really, bu then again, never LV'ed it up. :/]
Elemental Guardian and Ice Shield for PVE? Or not really? Worth investing points? [I don't use EG either, but I keep Ice Shield when fighting field bosses and invasion mobs. I prefer using Magicians for invasion mobs.
Guess the tank might appreciate Elemental Guardian. Or not really? (I also play tank, but so far, I've never really had any single Magi cast this on me. That or I didn't notice. And so far, it was never a problem that there's no EG. Maybe with all appreciate it, but you may as well keep your CP. 8D )
Learn how to Cancel Animation.. Helps I guess?
Either I run or hit on ESC? o_o But never had to as a Magi...as a tank, you certainly would. o_o
MCrit Dmg + MCrit Rate
[YES~ I'm a Crakshot mage myself. XD]
