CON has more healy goodness, but THM is the most broken shit ever atm. You want both to at least 20 (it only takes a few hours to hit 20, and that'll unlock Cure II, and Sacrifice II).

A recent Q&A mentioned plans to make THM and CON more unique/separated. The question was specific to CON feeling redundant because THM can use their spells and do everything better, so...


If you really want to play a healer class, CON will probably be the better/preferred healer within a month or two...or three...ish.

Whatever you choose to do though, cross-class abilities and spells are very handy- and CON & THM complement each other allllllll the way to 50.
