There is no such thing as "godly". If there were, you would see many posts asking for it to be nerfed (similar to a Touch Ranger, which is not godly).
There are powerful builds for the elementalist, look for build in the Elementalist Build Thread, Farming thread, and GVG forums (I think).
Every profession has its powers and weaknesses. Godly, to me, means you have insaine powers to hinder or obliterate anyone. As well as not have any weaknesses either. Sadly, Elementalists have inherent weaknesses, such as long casting times for some spells (like Meteor Shower), must rely on energy (unless you have lots into Energy Storage, you are subject to E-denial). Weak armor (therefore must have spells to increases your defense).
So if you want a completely offensive ele, or a completely defensive, or a balance between the two, I may be able to help somewhat.
There is no such thing as "godly", as Pick Me has stated. That is just silly.
Usually, GvG ellys I see nowadays - and back then too - were usually Ether Prodigy powered Air/Water Heal Party spammers (or in some cases they go with Domination skills).
Any suggestions,
along with builds XD
Water/Air ele with Blinding Flash and some freeze skills, no much damage, but very painful for all those assassins, warriors and ranger (touch ones included).
