1. Very hard to register. Took me a week to get the register button. 2. Cannot chat with opponent. 3. The controls feel "sticky". Takes a few presses to work. 4. Unreliable. Can't go into sleep mode for a moment without having to reconnect. 5. Crashing in teambuilder, thus having to start again, only to crash again. Being forced to use text import/export. 6. Closing window/tab logs out, and erases team. 7. A bit of lag/loss of frame rate in some battles, having to close the window which means I have to paste my team, and username again. I love the site, and would continue to use it with these problems, but I would like to address them.
