Greetings ladies and gentlemen,

I was wondering 5 seconds ago if IP boosts are worth the RP.
I am going to compare this, with buying a 6300 IP champion.
So let's calculate it:

Data
2 wins boost = 160 RP
50 wins boost = 2560 RP

1 day boost = 290 RP
30 day boost = 3490 RP

A 6300 IP champion = 975 RP

Win-boosts
1 win bonus in normal ~ 145 IP
1 win bonus in ranked = 166 IP
1 loss bonus = 0 IP

Day-boosts
1 win (of 45 min) bonus = 104 IP
1 loss (of 45 min) bonus = 63,2 IP

In the league of legends, you will found out that you take damage every once in a while.
Of course, we want to prevent that, but there are so many items for defence, including:
* Magic Resistance (MR)
* Armor (Ar)
* Health (HP)
* Health regen (HP/5)

MR and Ar have the same system, which reduces damage in percentage.
While HP basically "blocks" the damage as a number.
And HP/5 grants HP back every 5 seconds.
Let's ignore Health regen, we just want to see how much damage we can take in a row.

I have always used Armor penetration while a lot of other people use flat attack damage runes.

I have actually no idea which one is better by statistics, so lets calculate!

Data lvl 1
Average amount of base AD for an AD carry at lvl 1 = 55
Amount of AD gain from masteries: 3 + 0,58/level = 3,58 AD at lvl 1
AD runes grant: 0,95 AD each mark and 2,25 each quint
Armor penetration runes grant: 1,28 ArP each mark and 2,56 ArP per quint

The minimum AD at the start will be 55 + 3,58 = 58,58 AD
