This is just a random idea I had. I would think it would be interesting if there was the occasional 'theme' behind what champions make the free rotation. Some examples would include "Classic Week" where all free champs would be champs that were in the game at launch. Other ideas include weeks where every hero was either from Noxus or Ionia, Ladies Week, and Monster/Yordle Week.

Just to add a bit of flavor.

Also, ideas for theme weeks are welcomed!

Yordle Week. Amazing.

i like this idea maybe one week a month or something would be good

No, almost all the champions in a theme fit only one or two roles.

How about Champions were going to nerf into oblivion for no apparent freaking reason week? least then we'll know what champs not to buy.

I actually thought of this the other day. I had an idea for a "Siblings week". (Lux/Garen, Renekton/Nasus, Katarina/Cassiopia, Morgana/Kaye. With maybe Cho'Gath/Kog'Maw thrown in for an even 10 champs (I can't think of any better pair to fill it out)).
