Ok so I just did it 4 times the first,
Minimum 66ms, Maximum 69ms, Average 66ms
Second, Minimum 110ms, Maximum 286ms, Average 198ms
Third, Minimum 66ms, Maximum 162ms, Average 109ms
Forth, Minimum 66ms, Maximum 132ms, Average 94ms
And all of them no packet loss.

So I don't know what the deal is, but maybe you may have an idea this is what happens all the time. If I cast or use a spell or skill sometimes (every 2-6 sec) it will be interrupted if spell or if skill see it happen but no damage or let me use my next combo and then will be put on recast timer. So it is very aggravating when trying to play like monk or black mage cause I loss my stacks just cause of this and sometimes cant even use anything without the lag. -__- I also did not have this problem before about 6 months ago is when it started and have tried everything to fix it but to no avail.
