Combat Delay Lag

Hello, I recently purchased FFXIV a few days ago and have come across a problem that seems to be getting worse each time I play. Everytime I am in combat I experience a delay. At first this delay would just delay the ability by a few seconds. Then it would last long enough to the point where it would freeze the enemy in place for the time of the delay. When the delay is over the enemy I was attacking would jump to where the server registers it is and it is as if I skipped past 10 seconds of combat. It is at the point where this is happening in every combat situation and even during quest turn ins. I immediately went to checking my internet connection and other connection setting on my end but could not solve the issue. When I log in, the character log in screen always says I have an excellent connection to the server and I even went to check my average ping to the server through my command prompt, which was only 50ms. I haven't played this game for very long so im not sure if this is a very common problem or not but it has come to the point where the game is very difficult to play. I would love to continue playing this game but Im not sure I want to subscribe if I can't figure out this issue. Any help would be greatly appreciated. Thanks!
