I know this runs the risk of being deleted because it's another game, but hear me out. I'd also like to make sure that everyone, before forming a rebuttal (if you have one...), has tried the other game, too.
First and foremost, the main issue with Guild Wars pvp, beyond obvious balance issues, was the inability for new players to seamlessly enter the high-end pvp community. 8 man pvp does not group like say RA. Why not? There could easily be 8 man random groups but in a separate tier from the "real" stuff to at least allow players to get a fair shake and experience.
The second is balance. League of Legends has a 4 skill bar for each character and many characters. It then has two utility skills that you can choose from (and offers more as you level.) So, I am not going to say it would require the same amount of effort to balance GW with it's 8 skill bars and two huge pools (Prime and secondary.) But maybe that was one of the reasons why GW pvp was always imbalanced. I can tell you when you are playing League of Legends, it doesn't feel like anything is missing. It's still the same idea of rock paper scissors.
In summary (and although I could continue, I think I've said enough for something that might get deleted), League of Legends is a very simplistic format of pvp but it doesn't feel like anything is lacking. It's still just as intense as a GW pvp match. But it's more user friendly.
Think of AB. People might think that the format of AB was what lead to its popularity (its pvpve), but I say that the reason it was popular is it was level 20 large scale pvp that you could group into no matter what you "rank" was.
