I specced all INTrecently, with all Thoth gear. I did die bunch at first, while farming kills on AO2-3 which I previously did effortlessly STR specced. The trick I found was to make sure I know my targets and stagger the use of shield & debuffs as required. Mostly it's just a matter of running in, dropping some AoE, running away with auto on, then running back in as soon as lightning is available, which leaves most 3-5 mob bunches dead. If there is an archer in the group I make sure to have them pretargeted because they can kill me in two shots.
