First Victory of the Day IP Bonus should be in all maps.
We all know that the most maps played are: Howling Abyss Summoner's Rift Twisted Treeline
An idea to boost games on all modes, is to expand the bonus IP for the first victory of the day, to all 3 maps. Every 20 hours, i guess, we have a bonus IP for a victory, in any map. Mostly 100 IP, i guess. So, if you change that to 50 IP, and put it on the 3 maps, that would get people to play at least one match in every map. In the end people woulnt be getting too much IP out of it, because it will not be the same amount that it is today and would be a good incentive for people to play all maps.
