Guild Wars 2

I’ve noticed there are so many environmental weapons in game that could very well fit to be used in WvW too as siege weaponry, to help add some variety and strategy.

For instance, we have Hylek turrets and Asuran turrets, and why not, Mega-Lasers too.
Hylek elemental turrets may be anti-personnel weapons preferred by condition damage specialized characters. Asuran lightning turrets instead would work much like ballistas, but with a shorter range and bouncing projectiles.

Of course, the devices need some calibrating from their PvE version, so that they wouldn’t be overpowered or unbalanced compared to pre-existing siege weapons.

I have also an idea regarding Charr Battle Tanks.

They are never really used in game but could be WvW viable as means of dealing with large groups of enemies commonly called zergs, while being outnumbered.
It’s basically large moving fortress, capable of heavy defense and attack on both infantry and walls/gates/siege. That’s also why it should have it’s downsides, which could be: heavy supply demand for building, limitation to two units per borderland and perhaps being usable only under the [Outnumbered] condition’s effect (without it, the tank would be deprived of its skills and able just to be moved around).

Yet, it also shouldn’t be an overly easy task to control such a behemoth.
Being so large, it would also require at least three individuals with efficient communication and cooperation to be effectively controlled, thus making it the first party-controlled device. With one being in charge of moving the tank, another assigned to the front flame thrower and another for the top main cannon. In its upgraded version there could also be added more weapons (ex.: Defensive Spikes, Rear Turret) for more party members to a maximum of five.
Each control position would have its own skills such as:
[Heavy Treading] for Movement: Charge towards a direction and knock back multiple foes on your way. Range: 1500
[Fireball] for the Frontal Flame Thrower: Shoot a large fireball that rolls in a line from front of the tank, hitting multiple enemies and burning them. Effective against gates. Range: 1200
[Cannon shot] for Main Cannon: Shoot an explosive cannon ball at the target location causing wide area damage. Effective against walls. Range: 3350

While not being invincible, the Charr Battle Tank in the hands of a skilled party could prove to be a very effective weapon against large groups of enemies, giving a chance even to smaller forces to prevail in battle.

Feel free to express your opinion.

In gw1 good thing about charrs was siege devourers – maybe allowing players to obtain that one (for example from somekind of mercenaries after making event and spending many many supplies) – as a kind of mobile Catapult could be good idea? that would me IMO great
