Guild Wars 2

First, I do not know English. I am using Google translate.

Turret difficult to use, they can only be fixed in one place, and my enemies often use AOE them all destroyed. Or switch long-range weapons to destroy them.

I wish to have mobility turret, so that they become a robot is a good idea.

And I also want to get an engineer to summon the robot kits.

Also, I think the shape of the turret does not look good and I hope to get a sci-fi appearance. I am happy to spend money to buy this skin.

I think mobile turrets will make the engineer too strong.
The way to fix the issue is to give them the possibility to lower the cooldown of turret deployment.

For example, if you blow up your turret then the cooldown should be lower (the same as picking it up), but if you do not manage it properly and let it be distroyed, then the cooldown is standard.
Edit: I would even say that traited, the picked turrets should be abke to be re-deployed in under 5 sec; after all, you did go to the turret and spend some fractions of a second picking it up, there should be a big reward for that in my opinion.

Another improvement could be: either AoE spells should not affect the turrets, or the turrets take less damage from AoE spells (50% less with the possibility to trait for an additional 25% – Grandmaster trait).

As for the skins on turrets, I would like that, but I think it is not that important at the moment.
