Runes and masteries.
Am I the only one who misses runes and masteries? I feel like all the champs are cookie cutter now. It's almost like hey if you want this champ to preform well you have to take this tree. Before you could load up on AD AP HP CRIT Mana you name it and pick a mastery page to use. It just seems so devolved. I get that they wanted newer players to be able to compete, but what happened to grinding your ass off for IP to pay for runes to be able to compete. Just miss the old days, runes, seals, glyphs, cough (tribunial). There's no prepping involved you just play a champ and everything you need is right there. Takes the fun out of LoL imo.
