About utility mastery and suport/jungle item

1. After the duration of blue red and blue buff were nerfed by 30 seconds in 4.20, shouldn't runic affinity get a buff, since it was based on 20%?
2. Why the masteries that should help two of the worse roles in the game (gold income) are so weak? In utility you have Inspiration. That means nothing while you are laning with your adc. It will net some exp point ONLY if you are roaming and lost your lane. We have expanded mind that was used only with Ryze, and soraka maybe.

Why don't you dump the "obligatory suport item path" deep inside utility three? Remove sight stone and put a mastery at tier four that enables expanded trinket, letting you upgrade the yellow trinket making it stacks the charges faster until the limit of three? Buff the masteries bandit and scavenger, to replace frost queen and gold coin. It gets pretty old when I only get some free build path after dumping 1665 gold in a suport item and sight stone, in a gold starved role.

I feel the same thing in the jungle. Why do I have to start machete? We have runic shield (yay... a noob trap), ditch it and give us the machete passive for the skill, or split it in other masteries. You can even distribute the smite "buffs" into the masteries.
