Sorry SE, but endgame won't work if you don't fix something.

Sorry to say bro but your problems don't lie with the game.

I live in Australia. When I'm in Melbourne my ping is ~240. It's VERY playable. Things are responsive and dodging is visually correct. When I'm at work on my mobile phone internet, my ping is ~380. It's still easily playable. I have no troubles on any of the fights in the game. Ping, or the game, aren't your issues. It's more likely the problem lies with your house's internet cables, your modem or your ISP.

Don't blame the game for something that isn't its fault.

Your perception of latency is awry. Having ~380 ping would be EXTREMELY noticeable in any mmorpg when trying to complete reactionary content, and ESPECIALLY it is in this one. Saying that having ~250-380 still allows you to dodge things without problems is very far from truth (250 requires you to pay a really close attention to all the channels, which probably is not a bad thing making you grow a player), so unless you somehow shape space allowing you to make up for the delay I'm taking your statements with a huge pile of salt. In that case, my hat's off to you, great master of time and space. When I still played this game, there were a lot of Australian players trying to groupfind content - it's always been a disaster when they tried to avoid anything.
