Should Riot enlarge their QA team or lengthen new champ time on PBE?

So, Azir being able to ult the AI right out of towers, Gnar hopping on Camille until she dies from hyper procs, the recall animation cancels, the random glitch with Shen ult that took years to figure out (and a long list of other things that casually broke parts of the game like a drunk squirrel trying to climb a tree).

This is stuff that should not have made it out of QA, let alone PBE and onto the main game.

Personally, I'm for enlarging the QA team, since they're more likely to run through more permutations and fringe interactions than PBE players, though at the same time, PBE is generally better for checking balance in general.

Any thoughts?
