I have some ideas, and I'm not sure where to post them, so I'll put them here.
How about, instead of a "Lock In" button in blind pick queues, we had a "Ready" toggle button, and once everyone was ready, the game starts. What is the point of locking in anyway, why not a ready button? It would prevent auto-lockers, which are very annoying.
Also, what about the buffs slowing down (As in slowing to a stop whilst rotating aroung the player) as they run out? This way you could easily tell how long a buff had left whilst spectating.
Let me know what you think!
