New Tier 2 Masteries, anyone else disappointed in the choices?

Does anyone else think that the new Tier 2 masteries are kind of disappointing on most champions? I guess this may be a larger complaint, that the new masteries feel one-note but also they often leave no USEFUL choices. Unfortunately I have to take 2 of them. If any of these are actually useful for a mid/ADC/support, I'm genuinely curious.

Feast -- 20 HP gained on killing a unit (20 second CD, which is what makes it fairly useless. Good on a tank perhaps) Double-Edged Sword - increased damage dealt and also taken (this is the least bad one in most cases) Runic Affinity - Increased buff duration (how often is this useful unless you're jungle or mid with a non-blue-reliant jungle? i guess the buffs to fifth-dragon/baron are marginally useful) Secret Stash - increased potions and also biscuits, but now that they removed mana pots and nerfed HP pots are these even used anymore? Explorer - 12 MS in River or Bush is nothing. Old gave basically as much, as does a single MS quint, but those are useful everywhere Tough Skin - -2 damage from champion basic attacks was nice for tanks, but otherwise it wasn't very helpful (this is probably the other "best" choice in most cases)
