Opinion: Damage items are too slot efficient
I think a huge part of the damage issue is that items for damage dealers are over inflated with stats/slot... lets take a look.
You have your god tier slot efficient items.
- 3733
- 3600

- 3500
(lets not kid ourselves, titanic is MOAR DAMAGE
Honorable Mention
-3400 (He is almost there)
Now we have the top tier (minimal damage) defense items.
- 3100 (I guess its mostly defense)
-2900
-2850
- 2800
I honestly consider these two items offense items.

So where are my 3700 defense items? Why do damage items have so much tacked onto them? Why can't we just balance our item slot efficiency. Some games I see champions pick up Trinity force, and mercurial scimitar. Why can damage dealers have more stats than me just because their items are more slot efficient. Lets not even dare talk about gold efficiency of the stats that the items give, or how runes and armor pen make armor useless.
If we want to nerf damage, we don't even have to really touch runes, or champions. Just look at the gold/slot efficiency of all of the items. Its time to buff the tank items, or nerf the damage items. Damage is very excessive right now.
