Do bot games give just as much IP as regular games if bots are on intermediate difficulty and both games would go to same time frame? What about the 3's map vs. the 5's map vs. dominion? Also, I was told last night not to surrender because our team would get less IP than if the enemy just finished us off...is there merit to that statement? Do I get more IP if i'm in on more champion kills or creep kills? Just some things I've yet to find an answer to, thanks if you can pitch in.
This page has a lot on it about it: http://leagueoflegends.wikia.com/wiki/Influence_Points
Your kills/CS don't determine how much IP you get, only the length of the game and if you win/lose. Bot games give reduced IP depending on your summoner level and game type(beginner/intermediate). Custom games also have a penalty, and they only give IP for evenly matched teams.
Yeah just play, IP grinding is boring beyond fuck at early levels. Make sure to use it on important stuff (runes, runes and runes) and after a while you have no idea whatsoever what to buy with your IP. Using RP once in a while to buy a champ you really want can help.
At this point I just buy any champ on release simply because I can, if the 2nd skin is awesome as fuck, I just buy it with RP. The 2 runepage bundle thing is beyond good too.
Pretty sure for custom and bot games, you can only acquire IP for a fixed amount of time played each day? ie if you play customs/against bots for 4 hours, and the time you can accrue IP from these games is 4 hours, any more games you play will award 0 IP.
There is a limit on bots believe it is 3 hours? You get more IP if the bots are on a harder setting. Just practice PVP really. Don't want to get used to bots as they don't act like real players! Yes yes I know, stating the obvious but still.
