I agree that masteries could be improved, after all what's so fun 2 health regeneration every 5 seconds.

I don't really understand how your masteries would change it, infact personally I feel that they're more gimmicky than augmenting your champion.

Plus some of them would really change the feel of the game, or be incredibly unbalanced on some champions.

Precision - Cassiopeia would gain 10% magic pen, +3% damage on 'all' her Twin Fangs.

Numbers - I don't feel the ability to inflict 6% extra damage only if you're hugging your minion wave is very fun for the player who has it, yet it's bound to be very strong early game.

Patience - Way too strong, 200 CS is fairly easy to obtain, that means a 800 gold advantage minimum.

Insight - No offense it feels just like Wukong's passive, but with a bit that says if you see a new person you gain more defense. Also it's incredibly strong with immobile mages like Anivia who are frequently meant to get ganked, but is going to get 25 bonus resistances instead. So basically a nerf to all junglers and stealth champions. Also it seems to directly counteract Opportunity?

Meditation - You've overshot this way too much, you probably wouldn't even need a mana item anymore.

Inspiration - Personal opinion, but I think that masteries that make your champion able to 'catch-up' are the worst masteries, as they make you think "why would I want to catch up, when I can be ahead with the correct masteries". I'm thinking that Riot agreed with this too, as they removed it in the new masteries.

Runic Affinity - I do not want to see Mundo with 33% extra time on his ultimate. Or Vayne ult. Or Riven ult. Or Singed ult. Or Tryndamere ult. Or Kayle ult and E. Or Nasus ult. etc.

Architecture - This would feel horrible for both teams, +50 resistances, means that all siege comps, and it would extend the laning phase meta much more longer. 15% extra damage on your own turrets mean that CSing feels much more different for all laners who might opt into the mastery. Especially if you're botlane, where your support might get it, messing up with your CS as an ADC with you having no choice.

Overall I feel that the idea behind these are good, but they change the feel of the game or are just too strong that they don't feel like they augment the existing gameplay of a champion for some. Yet for others they do. The masteries drastically change the feel. Some feel gimmicky, others feel too strong on some champions, others just feel left in the middle - which makes it feel bad to have in my opinion.
