As for masteries i'd like to go 0-13-17.
More of a Hybrid build support.
A Must vs every ADC since you block 2 damage from Champion basic attacks
Increases your Bonus Armor and MR (Remember that it increases BONUS
armor/mr not your standard armor/mr)
This is another 1 damage you block from Champion basic attacks
The mastery explains it all, Extra health (on top of your Quintessences for some extra beefynes)
I'm putting 1 extra point in here since i already have 21 Armor trough my runes
Now onto the Utility tree
+3 Extra mana regen will be quite usefull since hooks are at an expensive mana price
Usefull in whatever trinket you take
This means you'll have an 10% Cooldown on your Flash/Ignite or Exhaust. Your carry will be happy
how usefull can it be when your pots are healing a bit longer then usual!
1,5 gold Extra every 10 seconds
This mastery is often misunderstood, it will give you an additional
20 health and 10 mana on consumption, so when you use 1 of these, it will give you the 150 health you normally get from health potions + the extra 20 health And
This mastery is so incredibly usefull since it will give you 1 gold for every minion
your lane partner is killing.
You will need the extra 40 gold to start with, I'll explain later why.
9 out of 10 times your adc will get ahead of you in terms of levels/Experience. when this occurs this mastery will help you get back to the same level a bit faster since you get 10 experience every 10
seconds while you're near a higher level allied champion (this doesn't mean that it only works with your adc, it works with every allied champion)
