Oh, you two.
I also started with the necromancer. I chose this class to pick a class I would normally would not play. To my surprise, it plays much like the Blood Mage from the Switch PQ remake. Loving it. Skull/Doomskull lovers rejoice.
Went to the Shaman next. Plays quite different, with requiring generation and management of poison stacks. Glass cannon, but when the class is firing on all cylinders, it is a sight to behold.
Moved over the Paladin after that, as that would have been the class I would have normally played first. Very interesting mechanic in play with the Paladin with generating Shield gems and then trying to NOT match them off the game board.
Most impressed that each of the classes I have tried so far have had very different playing styles.
