New mode - Hardcore mode

I think that this could be fun if done right. The idea would be to make everything punishingly more difficult.

1. no vision - no map, no wards, you can only see what is directly around your champion.
2. no hp regeneration - no hp pots, natural regen, item regen, or lifesteal. Of course mana and energy would still have to regenerate.
3. Minions, towers, monsters and champs all hit harder - tower diving would be 10X riskier, that lvl one harass that pulls minion aggro would be deadly. Taking baron would actually be difficult. Champion spells and attacks would do increased damage, etc.
4. communication would be the only method of knowledge - Pings are disabled, timers disabled, you dont know if your top laner died unless you see it happen or he tells you. You literally have no knowledge outside what you can see unless they tell you. You cant see item builds, deaths, or scores of friends or foes.
5. Summoner spells, runes, and masteries disabled - you gotta go in raw.

Of course any number of these could be modified but i think the idea would be fun to have a super tense, scary game mode.
