Absolutely not.
I don't use windows, and getting Guild Wars 2 to run nicely on *nix takes a bit of wrangling. Adding anti-cheat would shut out anyone using wine(*nix based operating systems such as linux or mac) to play GW2.
I've dealt with games not having a anti-cheat at one point then suddenly adding it and I get something like easy anti-cheat complaining that it can't properly spy on me from within the compatibility layer, therefore I could no longer play the game I had paid for.
Additionally, stuff like punkbuster is considered a privacy invasion as it includes built-in remote desktop(view only). This doesn't work with grabbing just the window, it grabs the entire screen. I do not want others to see my desktop, especially since I multi-task and there is some stuff that I don't want other to see(I.E. browser tabs, second life, NDA source code, etc).
Stuff like Denuvo uses 100% of your disk I/O for some unknown reason, and if your disk happens to be SSD, it'll significantly reduce the life span of it. (I.E. Damaging consumer's hardware)
When it comes to anti-cheats, there are only three types:
Aggressive, laggy, and intrusive.
Light weight, only detects known cheats and basic cheating methods.
Built for the game, spot on, non-intrusive and effective anti-cheat.
PB, Denuvo, and EAC both fit 1; VAC would fit 2; 3 don't have names because they are built in.
Are there cheaters in WvW? Yes, but they are very rare. Is it frustrating when they cheat in WvW? Of course. I've seen like 3 towers fall because a cheater portal'd in a squad and took it. Can anything be done about? Yes, report them.
Granted, the report mechanism is hit or miss, you have to be able to see the player and click them to report them. Doesn't help that you can't see player names in WvW either.
IMO, Anti-cheats are similar to DRM. The more intrusive the implementation, the worse it will effect the end user. Cheaters will get around it one way or another and may end up having a much better experience.
