Forget Wine for GW2. If you are lazy just install Steam & add GW2 as an external game to run with Proton.
If you are not lazy, then install Bottles, give it permissions to the correct GW2 folder with Flatseal & then download the soda 7 runner in Bottles settings. After all this make a default gaming bottle, then change the runner in that bottle to soda 7, enable latency flex to lower the latency at the cost of slightly lower average fps & play. (7 is better than 8-9 for GW2)
(Bottles has some minor advantages over Steam & you don't have to run the rather vram heavy & slow Steam client)
You could buy any Asus gaming mouse with user replaceable switches and order a bag of Huano silent switches from AE. (if the noise increases or the switch dies just replace the switc+h)
This is not a cheap option, but could potentially endure for a longer time.
