i suck at fire mage, but I'm pretty decent with ice my stats are from lv 1- 59 build to 60 vitality and rest in focus. then add 60 more vitality from 60-whatever cause I've never gotten a char past lv 60s.
and for extra energy in mobbing use esheild sacrifice or e boost combo, sac for out of combat, e boost for in combat.
hope i don't sound like a noob cause i am one and want to feel significant. :p
well, noob comes from newbie, and ur a newbie i assume (unless u play for a while and still low lvl)
again ofc u have done nothing wrong, u didnt explain about at least skills which are very important.
as for fire build
Skills:
Firebolt - maxed
Firestorm - maxed
Fire Attune - maxed
Fire lure - half of ur current max skill pts (to get mob's resist to zero or near zero, not boss tho)
rest of skill pts should go in that way:
if u want full dps : Ice Shards/Inc/Cloak (so armo wont say im giving same advices everytime), i personally prefer ice shards, mostly for the low lvls, i find inc working better, but for the long runs and not the short runs. Cloak is also good, the dmg is lower tho, but its a buff for 2 mins and 'unavoidable' (as long as the mob is attacking with melee)
if u have hard time surviving : E.shield ofc, costly, but extra dmg taken (since its not giving any armour boost or defence boost, its pretty much like extra health + auto regen) - i wonder as for improvments, if besides adding the normal shield bonus, would it be good to add armour/defence/elemental resists bonus (i guess since its energy, elemental resists would seem the most logical one, but mages need armour)
if u have hard time keeping up with energy : Either Sacrifice or E.Boost, most ppl would suggest e.boost (i havent really tried either, tried e.boost a bit pre update on h2h mage), but some find how to use Sacrifice in a very effective way
as for stats, stats should mostly depend on gear, any focus gear is great if u can get
