I have no problem logging in 3 accounts. The method I use is this log into the game normally. As it loads right click the black area so you can get the option for Frame then Show only this frame. It removes the toolbar at the bottom and top of screen and then bookmark that. You can then open the game already logged in and play on if you have other accounts all in the same window. My pc is kinda crappy but I used to do 6 accounts total before all of the merge talks awhile back when you still needed full teams to do Alliance Blood Battle, so on the dead server I wasn't at a disadvantage so..I do know what I'm talking about. My method works about 99% of the time, only need to log in via main site etc.. if you want to top up.
