So, i tried to focus more on defensive line in this bwe and i can say treb is really strong. It’s a good mechanics cuz it requires skill to aim, you can dodge and destroy it but probably it’s a bit too easy to repair.
I don’t remember exactly if in the previous beta you always needed only 1 supply to repair the treb but probably is a bit too easy with only one. Most of all if you use a class with teleport and high mobility like thief or mesmer.
To be honest with you I almost never see anyone using the treb and usually avoid it myself because I play LB ranger. But if it is any good then 2 supply sounds reasonable.
I save Ascalon against another Charr invasion, and my father trifles with doors!
