Uninstall? At least give it a shot first. Try learning the tactics to survive. Read the Hints-Ilych document which is in your Tactics folder, such as:
C:\Programs\BGII\tactics2\HINTS-Ilych.txt

*Perhaps* you'll enjoy the game by uninstalling this componant of Tactics, and going on to epic heroism in the wider world against later Tactics adversaries. But with a Kensai/Mage and the mods you chose to install, it appears you are ready for a high-powered battle-heavy game. I'd say go for it, starting right here in Chateau Irenicus. (You might need to recruit some NPC's briefly to escape this dungeon).
