Change is good when its constructive to the core philosophy of the game.
But honestly, That core philosophy has changed several times itself, and cant really rely on coming back to a familiar game if you take a few season break.
In my opinion? I'd say the changes have made it worse. Towers went from being strategic points needing dedicated planning on when to take them, Now its just "Rush them down, or wait for super armor to fade"
Dragon went from being a global jackpot of money to "Hey, Aatrox, Go solo that so i can kill this minion in 2 hits instead of 2 hits and a Q"
And while i will say that the Elder Drake was a nice addition, Giving an actual rival to Baron in terms of power, It really only succeeds if one team doesn't snowball a baron into an ED
