Teleport Home/Recall button (B) unbinding? Here's the solution!
I originally posted this on my home server (OCE) boards, however I figured NA may appreciate it too :)
Open a party with a friend (You must be in a party, as League Voice and it's settings aren't available any other way) Click on the League Voice icon (Little microphone on the bottom right) Click "Voice Settings" (Little cog on the bottom right of the League Voice pop-up) Under "Input Mode" click "Push to talk" UNBIND "B" (Set it to something that isn't used for anything else, leave it unbound, whatever) Open a game. Set your Teleport Home/Recall to "B" From here onward, whenever you re-open the game, League's config won't automatically force it's preset "Push to talk" back to "B" as you have re-bound/unbound it.
I hope this helps, as this was something that was surprisingly frustrating for my best mate and I.
