Retro Mode?

Something that would be fun for both longtime and short-time players is to bring back the Season 1-3 level of gameplay, complete with all the old items that have been nerfed or removed. I know how crazy of an idea that is, but it would really breathe some fresh air into the game. It could even be a rotating game mode or an annual event of some kind.

Remember when Master Yi and Katarina were the most feared assassins who, after snowballing out of control, could show up in a lane and make the whole enemy team run for cover? Remember when Sion's old kit allowed him to have 6k hp and made him nigh unkillable in the late game? Remember all the old items that were borderline broken like Malady, Force of Nature, Deathfire Grasp, and all those other sweet items that used to be in the shop? Remember when Teemo used to be a LOT more scary? Remember when all of Summoner's Rift had a different layout? Remember when unique passives used to stack (like 5 Warmog's on Volibear...back when Warmog's granted permanent hp per minion killed)?

It truly would be challenging, but incredibly fun to play the old season 1-3 game, before everything was changed after season 3. A lot of new players are coming in with no clue how hard, frustrating, and fun the old game used to be. I bet having a special "throwback" to another time would be something fun to feature for a week or so.

I still clearly recall the best worst game I ever lost. The enemy team's Karthus stacked 5 Archangel Staffs (each of them with completed stacks) and a Deathcap, and was fed like 30 kills that game. When he ulted, if you had less than 2k max health, you and any other teammate without enough HP would just die every 2 minutes. Frustrating yes, but honestly games were fun to lose when it was just that ridiculous.

Anyone else up for this?
