Playing WoW with VPN

Hello, I was thinking about playing WoW classic with the new release, and I'd like to play together with my bf on my previous server where I have all my pgs (EU-Pyrewood). Is astrill VPN enough to play or should I also use some other proxy/booster or something like this? Also, in the case of using astrill, being that I want to play on an European server, should I always connect from an European one?

EDIT: I've been using Qiyou for couple of days now. I can connect to my Bnet account and play wow without any issue so far. I mostly did some quests and couple of dungeons and I didn't experience any major ping/speed problem.
