The game was just a lot more fun to play and you didnt have to worry about someone being completely busted because of a keystone(or rune in this case). Tbh I would rather have another mastery tree to choose from than what we currently have
I wonder why they haven't simply followed the new Keystone system with higher base HP for every champ in the game. I miss the long teamfights and even having the option to build certain champions in a more tanky direction. Offtank 
was very much a thing prior to the patch. Sure, you lost a lot of damage and utility, but could really wade into fights and position for optimal Q stuns. Now, unless you're an innately tanky champion building tank items has nearly zero impact on keeping you alive longer in this high burst meta. I suspect it's partly mpen/lethality, but the results are clear.
There were keystones before runes reforged.
No one likes changes, especially when things are so new and no one knows 100% how to play against them. Plus things will be getting nerfs and everything in the future so things that are strong now won't remain the same. Give it some time and see how it goes :)
