is it possible in the future that the Demoman can regenerate his shield in saxton hale, its verry boring to lose the shield
Haha no way, the demoman has already some advantages what makes him overpowered enough. Like shield and heads, if you got 4 heads, you could still survive one hit.
3 engis should be able to team up and build a forcefield out of 3 connected dispensers(triangle shape) and if saxton walks into the field he cant move for 20 seconds. For every additional dispenser the forcefield gets stronger and he cant move for extra 10 seconds. No this is not overpowered.
