Client issues

I don't think anyone can deny the new client that was introduced (2?) years ago is a huge improvement. But why is it I encounter a new bug on the client almost everyday. Theres been issues with the friends list since the start of the season. The client always has issues loading certain tabs like stats or the loot. Not to mention the random freezes and disconnects in loading screen and the constant struggle to even open the client sometimes. Like how are there always constant issues with this client that never seem to get fixed.
