Client bugs

Ok seriously, these bugs have been around for so long it's awkward now Every new patch is like a new adventure, what kind of new bug Riot implemented this time?

Why is the client so bad, sluggish and overall buggy? This is just a few of the things that happened to me:

• Friends not appearing in friend list when they're online
• Friends being in game for "87 minutes" or something, while they are playing another game all together
• Click "Accept" for the queue; "You have failed to accept the queue"... and no, not an internet problem
• Random bugsplats every fucking time, they come whenever you don' expect them or when you go take a piss
• Friends in a group, going back to "General" group tab
• A multitude of champ select bugs, not even going to list everything or the list will be infinite (runes, ward, sounds, timers, etc)

I mean what the actual fuck come on
