Hey I've recently started playing again due to the outbreak/ boredom. One of the main reasons i stopped playing was due to the buggy, hard-to-navigate in-game client which made playing the game un-fun. However I have recently discovered that a lot of the issues I had were reduced when I took the game off full-screen mode and made the game windowed. Having the game in windowed mode as opposed to full screen makes moving champs around the board a lot less choppy and you're less likely to mis-click. You can also use your number keys "1, 2, 3..." etc to activate your champions attacks and abilities (having tested, this isn't possible in full screen mode). It's not perfect- but much better. If anyone else has any other tips on how to improve the usability of the client please share. Hope this helps anyone currently playing or coming back to the game like myself. Devils.
