Noob Questions
What i don't know: What's a good amount of scaling for stats like AD, AP, Armor, and MR? How much CC (Slow duration, slow amount, stun duration, root duration, etc.) is good? Do all stats grow as you level? Do i get MS per level? How much Life steal is worth going for as opposed to Armor or MR? Is going for a large amount of MS good and will it ever be useful?
or get

4.What champ? what role? what build? need more bud.

use move speed very well and is usually a core item or mastery or rune page for that champ, especially tank junglers(not so much currently but used to be). And
is core item for supports.
for example.
This may because your team has reliable tanks and engage so all you need to do is sit in the backline and throw the cage to protect the backline and nuke people. If your team doesnt have the engage and front line you may build him a little tankier because he still scales his own AP and being able to get close and trade is more necessary.
instead of
because the enemy has more ad champs.
. Significant amounts come from items or ability passives such as veigars AP stacking passive on his Q. Or Ryzes mana to AP stacking which again comes from items.
is such a problem now.
, now this item is only 20% but it is core much like
is for champs that need to "stick" to targets. It isnt op it just gives a little help, again any cc effect that is longer than 1 second is usually annoying(or op, cough sej).
4.There is basically no spell vamp in the game now, so dont buy lifesteal for AP champs unless
. Life steal is for ADCs and certain bruisers. The only reasonable item you are refering to is
. Which you dont build on Eve, see with squish champs lifesteal is the ability to gain health back, which is outshined by pure health or hybrid(by this i mean heltha nd damage not AD and AD) items like
etc etc. Since you survive longer in team fights instead of dying by TRYING to lifesteal. look up recomended items for your champ and in time youll learn what builds are.
