Guild Wars 2

Problem: In their current state, turrets are too fragile and they do not grant any other additional utility (except a single high cd overcharge skill) to justify choosing them over a kit

Suggestion: A grandmaster trait that would encourage the use of multiple turrets by (1) linking the hp of the turrets deployed, (2) reducing overcharging CD based on the number of turrets deployed, and finally (3) granting stability when two or more turrets are deployed

(1) e.g. A rocket turret by itself can take 7470 points of damage based on its hp. Given this trait, the damage that this rocket turret can take increases based on the hp of the addition turrets deployed. For instance, if a player deploys both a rocket and a rifle turret, both turrets can take 14940 [7470+7470] points of damage before being destroyed. But, since they are linked, if any one of these turrets receive 14940 points of damage the other turret will also be destroyed.
(2) A 10% reduction for every turret deployed
(3) Grant 5s Stability every 5s to engineer and allies within a predetermined radius around the turrets. [Engineers need a steady source of stability to be able to stand around the turrets to repair and defend it]
*healing turrets not included in this trait

What would happen as a result of this trait?
This would spawn a class of point defense turret based engineer who would take turrets on two of their three utility slots and take the tool kit for their third utility slot to heal their turrets. Since the turrets provide AOE stability, they would be valuable support for allies defending or taking points. Given the lack of damage output and cc [no grenade or bomb kits], an engineer should not be able to overpower multiple opponents to take a point by himself but he should be able to hold a point against multiple opponents with the help of properly placed turrets.
