I never had much problem playing a thauma, I find it fun, although it does not bring much to the table at rank one, but I cant help thinking sometimes that, looked at from a rational point of view, either this class makes no sense or the NPC who invented it are completely stupid.
I mean…
they invented a spell that is capable of buffing enemies: swell body (an most probably the most op buff in the game. It double HP, increases attack/magicdmg by 60% and increases AOE def ratio) but they didnt get the idea of using it on themselves.
While having the arcane knowledge to instantly increase HP (swell body) on several targets and a full HP bar not an empty one they invented a spell (transpose) that does something similar on 1 target (themselves) but with an empty HP bar while they have no easy way of healing.
It’s funny to imagine how thaumatures must be seen by NPCs from other classes within the game, crazy guys you cant determine whether they are geniuses or idiots.
