physical vs magic damage
Over the last couple of months ive noticed there has been this trend in overpowered physical damage items with little to nothing on the magical item side.
for reference there have been a good couple of patches in which a ad item has been considered overpowered such as with BotRK, death dance and most recently Duskblade as well as the minor constant changes to some other ad items such as when they add 5ad to a handfull of lifesteal items or reduced the cost on IE without changeing its stats. another example is with lethality and how its constantly bungying between too strong or just subpar and with the addition and buffs to addaptive helm it feels like magic damage is being nerfed down in favor of ad.
like even mundo just got tweaked to be more anti mage with his passive magic resistance buff and the only thing ive noticed that has helped mages is by removing the mr on edge of night
(this is all based on what ive seen and appolagize ahead of time if ive forgotten to mention and or have missed some thing or have false information or interpretation of the patches over the last 3-6months, and im free to any comments or ideas that you believed ive missed)

, but when is the last time a SINGLE AP item got buffed in any way shape or form? Except for a 100 gold price decrease.
And at the same time, the items have been getting nerfed in terms of slot efficiency since the MYMU.
Will of the Ancients got straight up removed
(Unless you're Karma or Lux) and if you were close ranged, 10% more magic damage
. Meanwhile...
buffed
Added, buffed
Added. Though this one at LEAST also gives armor and is only broken on
Passive buffed. Now you have to burst even harder to get the same stuff done.
Buffed (Yay)
so that's cool
as a new item, which is basically just a crappier version of 
A lot of it is damage from waveclearing in the cases above, but that's still an important strength which magic is clearly excelling at.
Also, top 5 average number of kills are
, which is 3/5 primarily magic damage.
