Bring back Legacy Client

This Client just sucks and we need the old one back. Seriously, do I really have to mention the bugs? well... here we go:

• Errors on picking your champ when theres 1 sec left to pick
• Post-game Lobby not loading
• Your status still says that you´re in-game even if you have already finished the game
• You can´t invite your friends because of the bug above(it says that your friend is not eligible to join a party)
• When you don´t have low-spec mode activated some textures of the client bug
• The client sometimes saves your account credentials even if you didn´t allow that option and many more...
