I have no idea
I always use the Tech1 Predator MK3 Tank. I gues it should be more an Tech2 then a Tech1 tank.
There are many balance issues like this. Maybe, if i have more time i will change some things like this.
But this is not my mod. I only update it, and don't want to change things. Because i dont know, why those thinks are, how they are.
Of course if there is a big balance problem, i will handle it as bug and change it.
We can move the Predator MK3 from Tech 1 to tech2. That's ok.
But i don't start to change any health or damage values
