1 into TS either way... the dmg wont vary much with your maxed LM anyways, my sorc has lvl 1 TS and it does about 2.3k dmg. I experimented with maxing warmth as well, but I think if this is a PvP build than you won't have tooo much time to regen mana anyways, I have a lvl 1 warmth, and it barely takes much time... I can just go tele away and wait 15 seconds to regen most or all of it. If you wanna spend those 19 extra points I would suggest maxing out Frozen Armor for melee chars, or maxing CL, for the extra lightning dmg. Lightning can be used on those annoying absorbing zons, who will only take dmg if dealt in huge amounts, with my sorc, more zons feel nothing from CB, but lose up to half their life in a hit, or even die from a shot of Lightning and the dmg is only 21k (no maxed CL) :bonk:
