guard's treants

[SCorpA1]

and because he supports, the range of the tank cannon is too less. he is not in the fight, more at the edge and if he is rooted he cant move.
what i want to say is:
the guard have to be rooted to be eefective, thats good!
but if you are roooted, and you are too close to the battle you die easily, because you cant moce.
and when you are rooted right in the right range its too far away to use the tank cannon.

conclusion: often the tank cannon is useless and it would be nice, if it would be replaced with something else

also the active healing spell could replace the tank cannon and the treants upgrades the active healing


Edit:
i think 5 are too much, too, because treants looks really strenght and heavy and are qualitve, but the ghosts of the ghost tank are more quantitive creeps
2 big bad treants ftw
