Seriously, just make a alternate way to get IP. Like, minigames or something. IP farming for PRATICE games is getting a bit obnoxious.
To clarify, it'd be kinda annoying to remove IP from pratice games, because then it would demotivate a goodly number of people saving up for runes/champs/whatever to just have a trail by fire with new champs/builds. But it would still be nice to have a alternate way of making IP on days where we don't have time for a full game, but still want to make some IP to save up for a new champion, also hopingly encouraging IP farmers to just use the alternate revenue sources, thus cutting down on the massive amounts of IP farming games clogging up the pratice browser list.
