Tactician mode is planned. Until full release, all we'll have is classic and explorer, as they want tactician to have new enemy placements to make the game fresh. To know what'll be fair and what won't, they're probably going to reserve constructing the new enemy placements and enemy skills until the end of the development cycle.
EDIT: "Strategist mode". It's the first stretch goal on the Kickstarter page.
