Standalone Reworks/Updates vs. Reworks as part of Class Updates (I'm seeing a trend)
I've noticed a trend over the last season or so. Standalone champion reworks that Riot do have been great. Meanwhile champions that get reworked as part of Class Updates are pure cancer. Kog'maw (reverted), Quinn (Olaf'd) and Graves who is still pure cancer and slowly getting nerfed out of favor. Now with the assassin update. I'm happy with Talon, Katarina (numbers tweaks should put her in a healthy spot) and Leblanc. The rest are pure cancer or rubbish.
I feel like after a while quantity starts to diminish the quality of what Riot is releasing, and this becomes dreadfully apparent when they do whole class updates.
