Bring back old masteries and runes!
The new runes are just very unfunny. There is no unique playstyle in it anymore. U have a few options now to build with these runes unlike old runes + masteries when u had just so much stuff. There was more fun in masteries because u could take whatever u wanted to. Now if u try to experiment (which still is hard to do with amount of things u can choose) and pick bad runes u just lose ur lane and probably game because runes has too much impact now. Also amount of builds u could try with old RUNES was crazy. U had sooo much statistics u could try out like for example crit dmg, gold per sec and so on + u had places when u just could not place some rune in like marks because this was non-optimal so u had to figure out that too. U had to spend some time before the game, u could not do ur runes in the game now it's like 1/2 old masteries that very few are optimal to take. Also, i think that high cost runes was good. This runes and masteries rework killed the game kind of to me. Soloq would be so much more fun to play with masteries AND runes from season 3 when there was no thunderlords and stuff just pure fun.
