One last thing i want to point out: Current sytstem is bettee for new players, the game ans riot for the simple fact: "Unlocking stuff is exitement". Look at Dota, how many people play this game even if all heroes are available from the start. Look at league, the champions you have to unlock, the new blue essense sStem, the runepages now.
People who not have already having everything unlocked but got used to the ip system flamed a lot on the boards cause they FEEL, they get less.
On the other hand imagine new players today and new players pre prrseason 8: these one got ip and exp from, from every game a little bit. Yea, first win of the day was exicting but than you had to decide which champion you want while proberly not even have played 10 out of 140 or if you even wanted to purchase runes or runepages. And at lv 30 no more exp, just ip but by having acces to 20 champions you could now play ranked. Geting from lv12/18 to lv30 was nothing special either, all important stuff like the keystones and summoner spells were unlocked.
Now: You get now just exp after every game but Be or Championshards at every level up via capsules or Boxes (first 3 lv you get ashe, Garen and Brand for free). Yea there is this sytswm by earning sto get boxes and rng championshards could help you in the decision if you want to get this champ, convert it into be or test him for a week. Loot, Loot, Loot, things every good game has: Looting and Leveling. Gues what, leveling goes now beyond 30 to, so at 30 you unlock rankes but still can level up farther for even more loot. That excites new players and excited players are good for riot. The boardstorm is nearly over too. Ofc be is not perfect at fhe momenr, things can change foo. But look, there is a varus lore chanve, now people already forgot for gods saks about be rant.
Coming back fo runes: to unlock them over time makes leveling and by that playing just even more eyciting. Ofc you can wish to have every champion available atlv1 but it fewls soo good to have earnes it by playing the game, eypecialy at the begin. I feelt so much more joy getting my first 10 champions as now, getting like my 110th champion. I don't play everyone everytime. And i also still have not uses every of the 60 runes nor will i probably use some runes as much or even entirly as others.
