The new client is STILL really laggy for people on bad computers

Those of us who started playing League before the new client update and played it because it was one of the only games that would run well on our toasters have been upset about the new client ever since they retired the old client. Me and a couple of friends still get horrible lag in champ select, enough that several times we've had the wrong/incomplete runes and masteries or dodged because we clicked on a champion but didn't preemptively start spam clicking the lock in button 5 seconds before hand. Not to mention it makes the whole champ select process much more stressful than it needs to be. The old client ran fine for everyone, the new one is cooler but not really usable for a lot of people. I and many others would like to see some optimization done so that we stop getting trolled by the lag in champ select. We've been saying this for a long time and it feels like no one is listening. Would appreciate some feedback on when or if that's gonna happen. Thanks
