I don't like the new leveling system and the BE it offers.

Idk it just feels clunky. Too mmorpg-ish.
I just want BE after a game. Has anybody done the math? Is the time and effort put into leveling up and getting BE worth(which may give you crap and useless shards) the same as steady IP from winning games? I liked looking at my IP every time i lost/won. . Now its just RNG(meaning there is no guarantee that if i play X amount of times I will def get this champ)I have only leveled up from 30 to 31 and got crappy shards so I am still new to the system. Maybe i just dont like the new leveling system or i am blaming my bad luck. What do you guys think?
