The problem in my case is not with facebook, is with my portable, is full 99% don't have space and lots of programs working when I open it. If I close some of this programs, in 15 seconds I can be loged in the game, and in 15 more, can add all the skill points and change 1/2 team of position...
too google chrome have problems with the "complements" sometimes, and it goes slow, and it's stopped, so I think that all is not the game, or facebook, for sure in lots of cases the players can do "something" to have a faster CPU...
