Recommended items: Riot specifically said these are "safe" builds for beginners.

There's already a backend in place to locally set your own recommended items, which is used by some item changer programs.

RP->IP conversion, if ever done, would need a cap per month/year or something like that or people _would_ find loopholes to rush vast amounts of IP for runes, resulting in power being sold for real money.

More percentage penetration: no. Just no... 0.9 * 0.6 * 0.75 = 40.5% left or 59.5% penetrated -> you're pushing tanky DPS/tanks to buy even more health instead of resistances... Fratmogs here we come? :-(
