It should be noted that the client and the game are two completely separate pieces of software. The game itself certainly has a bunch of bugs, but those bugs tend to not be game-breaking, and are mostly "this doesn't behave as described" - for many of these things, it's not even clear anymore what the intended behavior even is. Until it's fixed, it's intended, for better or worse.
But apart from that, the game is actually somewhat bug free.
The client however, is just an honest to god embarrassment. It is legitimately terrible in every aspect that could possibly be terrible. It's slow, so slow that many things temporarily break on laptops, like opening rune pages in champion select. It uses more RAM than the game itself (?), it runs on like 4 different processes that interact in who knows what ways, but if the client crashes and you're trying to kill it that often (but not always) initiates a repair for no apparent reason. Often it doesn't even shutdown properly when you close it. On a friend's computer it one day just died and didn't start at all anymore, with no indication of what went wrong. He had to reinstall the game.
It's a mess. And not only it is it a mess, it's an embarrassing mess because the client was always a pain point of many players, until they decided to completely re-write it in 2015. From the ground up. Clean slate - scalable, durable, lightweight, all that jazz. And now it's widely regarded as worse than the original client. If there was ever an example of how not to rewrite something, that would be it. Just a catastrophe on every level.
