Without using a VPN, a latency of 300ms makes things like Titan Extreme a gamble (I've only been able to get through it once, must have been a lucky day with my connection).
By connecting through WTFast's New Zealand server via a chained server directly to Montreal, I've been able to reduce my lag by a tremendous amount from Australia (see attached photo). I'm actually in shock by how low it is, and I don't even know how it could be physically possible!
Look at that, 300ms down to 42ms. /drools
If you're having lag issues, I highly suggest a VPN like WTFast, Battleping, or Pingzapper and selecting servers that offer you a better, more direct route to FFXIV's servers in Canada.
Has anyone else had lag issues, problems with content like Titan due to it, or any success with a VPN? Share here!
