Support item changes delay the quest finish and hurt warding
So my personal experience after this change is that it seriously delayed my achieval of the quest and thus i got the wards not in minutes 9-12 but now it's more around 12-15 on average. It's pretty significant.
Defending the turret alone basically is not worth it anymore since it doesn't progress me on the quest... Heck sometimes when i am zoning enemies from farm and my adc is close to the turret and i am at the middle of the lane i hit the enemies and don't get gold for it.
