I agree ele is weak. I do fine on necro and with mesmer I can take champions down safely all 3 i have around lvl 60. Thief I had to play with to get a good spec but now i do better than fine with it. Warrior had to go defensive spec any weapon will do on him. Guardian is fine any weapon any spec . Ranger if very good with 2 tank pets i have no problems with ranged weapons.
I just cant get through some areas with ele solo so i pretty much dont play him just my opinion but i did give it a good effort with searching for builds/tactics and trying them out.
