This is one preview of the future you don't need a mystic to see.

Charabis has overhauled his Gods and Heroes: Rome Rising class preview of the Mystic for us! There's more information now than ever, including the special minions Trevia and
Bacchus grant their followers. While you're there, don't forget to drool
over the pictures that have been added throughout the article. You won't
be sorry.

Within the article, Perpetual has confirmed that the Mystics
do have crowd control abilities. The picture above is believed to be one such spell, although the name of it is not currently known. Combined with Damage over Time and instant damage spells, the Mystic is sure to devastate anything they come across.
