The ping is unstable during the week, sometimes dropping as low as 40, up into the 200's for me. Today it started around 250, but has been hanging around 100-120 for the past few hours. (10AM EST- 12:50 EST). This past weekend it was a solid 255
This is of course my own experience, YMMV, etc.
It really sucks not only to lose out on the ability to get some of the more end game focused tames, (Rock Drakes, Reapers), without an added level of difficulty caused by lag, but to not be able to do much during weekends or prime time weekdays.
I hope there's a more permanent solution to the problem, as the previous fixes did work, if only for a little while.
Edit: 2:22 PM EST ping dropped down to 55.
