After 9 games, I got my champion capsule, which netted me 810 BE.
If this were the old system:
According to the League wiki, the IP you get is generally as follows:
Wins: 18 + 2.312 p/min
Loss: 16 + 1.405 p/min
Bot Win (Lvl. 30): 18 + 1.85 p/min
http://leagueoflegends.wikia.com/wiki/Influence_Points
Those 9 games were composed of 2 ARAM games (one win, one loss), 2 Bot games with First Win of the Day active, 3 won games and 2 lost games
Game 1: Bots, 17:31 (49 IP + 150 IP FWotD = 199 IP)
Game 2: Draft, lost, 27:10 (54 IP)
Game 3: Draft, won, 34:06 (97 IP)
Game 4: Draft, lost, 23:11 (48 IP)
Game 5: Draft, won, 38:40 (106 IP)
Game 6: ARAM, won, 21:51 (66 IP)
Game 7: Bots, 19:28 (53 IP + 150 FWotD = 203 IP)
Game 8: ARAM, lost, 16:54 (38 IP)
Game 9: Draft, won, 32:55 (91 IP)
Totaling 902 IP. And I didn't round the times up for Game 6, 8 or 9. If I did, it would probably net me maybe 910 IP
So the new system gives you less IP/BE than the old system. Instead of grinding just enough to get a new champion, you might be a couple BE short of getting a champion you REALLY want and you'll be stuck 2-5 more days until you level up, and then you'll have an excess amount enough to buy 1 or 2 450 champions.
Combined with the old players complaining that a 975RP skin way back then is now worth 150K BE, and players complaining (including me) that games have become way more snowballing now, this is probably the worst update that League as a whole has been given, at least of what I've seen
