For one Tech x is the wrong unit to use... until it gets a turning speed increase tech cuz they go all over place when you try to move them. With the insane damage and splash/flame pools of the event units they take heavy damage. For me I only use the tech x with proton tech as support for devin for the rushing units on start, then I retreat them.
For ch 1 to 4 I only use Devin, Asmondeus, proteus, orions, apostles and 2 tech x as needed.
