Riot, the New Client is Unusable on Some Rigs

I play on a standard laptop without a GPU, so not the best setup in the world. But with 8GB of ram and absolutely no problem with the legacy client I shouldn't be forced to dodge a placement game because the client won't bring up the champion list fast enough for me to ban. I'm not the only one with serious lag issues either, just bring up the topic in champ select and people will tell you about how much slower it is. I was in the LCU beta, and up until about a month ago it was laggy, but playable at least, and that was before I put in a second RAM stick. Until the new client is actually fast enough to run on lower end pcs Riot shouldn't force people to use the new client
