Boots of Mobility - Change the Passive

As of right now, Mobility Boots are very weak because of the change that happened with 4.3  They have the same MS of Boots of Speed when in combat, lower than any other tier 2 boots in the game.  The trade-off being that when out of combat you have more MS than any other boots.

Because of how harsh the MS drop is between in combat and out of combat, I think that a better factor for determining whether you get the speed should be the last time you took damage.  Essentially, make Boots of Mobility work like Miss Fortune's passive, Strut.

This would mean that as long as you yourself don't take damage, you're still moving quickly.  It would reward players that avoid being hit while fighting and would change nothing for champions that are taking damage before they deal it.  It would also put a larger emphasis on kitting Mobility Boots instead of just running from people with them.

Alternatively or Additively:

Since moving between camps is one of the problems for junglers, make it so that the boots don't go down to 25 MS when hit by neutral monsters.

Runic Blessing - Make it Slightly Less Awful

So everyone has seen that tiny shield that some people get at the start of games (Not talking Granite Shield from Malphite here).  To say the least, the mastery is bad.  50hp shield only when you respawn.  In other words, in order to take any kind of advantage from this mastery, you need to die a lot.  And even if you were to die a lot during a game for good reasons, like in kill trades as a tank, it STILL has almost no actual value as a mastery.  Especially when you compare it to the masteries on the same tier:

Second Wind - Increases all self-healing effects by 10% while below 25% health.

Legendary Guardian - Grants 1 / 2 / 3 / 4 armor and 0.5 / 1 / 1.5 / 2 magic resistance for each nearby visible enemy champion within 700 units.

So, you can either have a few 50 hp shields, one every time you die, or you can have 10% self healing at critical health or up to 5 armor and 2.5 mr for nearby enemy champions at any time during the game.
There isn't any kind of contest between these masteries.

So, my suggestion is that the Runic Blessing should be refreshed whenever you are in the fountain and out of combat.  Somewhat like the Crystaline Flask.  This would at least give the talent a small bit of worth compared to the other masteries on the tier that it's on.  It would still be inferior, but it wouldn't be completely terrible.
