You could always make it random then put an affinity on champs when they get put into the free week making them less likely to be used again for a period of time like say 2 months (time can depend on the amount of champions available and how many are free each week) but always have 1-2 recommended champs for the new players. As well the affinity could build up on champs if they were played within the same month or so. ie teemo and riven r free he same week, then next week teemo comes up again so teemo's affinity to be chosen drops by double or something and the timer resets for teemo to lose his affinity. This however could get a tad bit complex if you were to incorporate the positions the champions play. But you could always put in a champ that could fill the majority of the roles like cho gath or master yi

this came out a lot longer than I intended... o well

A pattern where all champions are previewed eventually. I've seen dozens on dozens of champions put on the free week multiple times, and other champions never put there. It seems more like a "Pick twenty champions to rotate for a month or two" then anything.

how about make all 450 IP champs free always, or maybe have 15 free champs so more can see the light of free week

do you accept some requests for summoner creatures sometimes? and if so, could you add Shyvana to the free ones next week? i obviouslly like dragons and so would really like to be able to test her out and see if i am any good so i know whether or not it would be a waste to buy her.

What if you made it so the players could choose one champ that they would get to use along with the free champs? that way if there's a person that you've really been wanting to try before you bought them you could make your own choice

i think the rotation is almost fine, just would make the number of freeone's bigger, like 10 or 12.
And i liked Ochandor's idea, of choosing one you like to try for free week, you would just need to make that you can't choose de same hero in a determined period. (like a month or two.)

There should be a pattern like, 3 champs below 4800 ip, 3 4800ip champs, and 2 6300 champs. Just a suggestion.

You said "We listen to player feedback on Champions to make free" ... So how does one go about suggesting or requesting a specific champion for the next rotation?

Thanks

I think thats a really cool idea

Make all the 450 ip champs free all the time? What would be the point of putting them for sale? I do like the 15 free champs idea though.
I'd like to add something on about suggestions though.
It would be a little wise to create a system where you could test champions for a small IP price. That way they have played them a game, tested if they enjoy them, and see if they are going to buy them. This option should only be available for 1 game per champion to avoid overuse of it.

There is one champion i have not seen free other then the week after she came out, and that is Diana. I didn't have the chance to play her as i was on vacation. I'd really like to see her be free one of these next few weeks, if you take champion rotation suggestions.
