OK, put a dwarven bombard on the space right next to the middle cave where the wulfs usually come out. On either side of the middle path, put three mage towers. Then build a barracks so that you can move the men to block the bridge. As the battle lengthens, upgrade the mages on the top of the middle path to Arcane wizards, and the ones on the bottom to Sorcerors mage. Upgrade the barracks to Paladins and give them the holy strike. Also its a good idea to fully upgrade the Sun tower and use it as much as possible. Fully upgrade the Bombard to Big Bertha.
As you fight J.T, buy the Deathray for at least on of the arcanes. Buy the rocket launcher for Big Bertha, and get the Elementals from the Sorcerors. Let me know if this helps.
I have builded only muskets on the upper line and it worked for me as well as releasing them fast and using all the meteors and the Sunray Tower on him.Headshot also really works.Also place the reinforcemnts on him because even if they aren't afeecting him,they stop him for 3 seconds.Elf archers are amazing on the middle line and a death ray wizard in the up right middle line and a sorcerer on the low part with his elemental on the upper side will really stop him.Use all of your stars on Archery,Meteor Then Mage.I didn't used any dwarven bombard.
