I never had a lvl 70 twink, but I do have a shaman as my main character. Some tips with playing ele: when a melee opens on you, put stoneclaw totem( remember to take the stoneclaw glyph that gives you absorb aura), and immediately put earthbind totem down ( remember to put talents in earthbind totem so it roots them ), don't worry about stoneclaw totem because when you put it you get the absorb aura and it will stay on you even if you remove stoneclaw totem.. Then put flameshock, instant lava brust, run around and cast lightning bolts ( take the glyph so you can cast lb while running) and put stoneclaw totem + earthbind totems when off cd. Also use thunderstorm when you can. As elemental it's so easy to get melee of your back.
