Take this with a grain of salt, as I am not a Lawyer and this is all just info I pulled from reddit.
Apparently there's a specific Canadian province that has some really funky internet privacy laws that pretty much makes it a safe haven for all things private-server related. Something about the parent company having to prove they handled personal data 'up to spec' before they can do anything. Which.. given the potential user data leak; is going to be a catastrophe for NCSoft from the word "Go"
Sadly I cannot find the 'source' (but I read it on multiple occasions, and even once about Epic Games an account hacking incident) nor do I remember the specific province, but maybe this can serve to give you a little peace of mind. Homecoming seems to know what they're doing. There's got to be a reason they chose Canada, and that specific host etc.
Also, as a US user I have not experienced any detrimental ping outside of rubber banding once in awhile. Unless the servers were about to croak. So I suspect Ping for the EU users should be fine.
The Homecoming Team is awesome. I trust their decisions cause they are on top of it!
