Season 4 Support Idea
My girlfriend and I were discussing support changes for the next season since she mains support, and we thought of perhaps a mastery point that reduces ward price moderately deep in the utility tree (unlocked after spending 13 points). We haven't spent too long on crunching the numbers, but logically off the top of our heads, 40g is far too low, 50 is eh, but 55-60 seems about right, with pink wards either having no reduction, or being reduced to about 100g, making them have a +5g effectiveness on killing full price green wards for more incentive to pink.
As I said, this is still in the brainstorming phase and the numbers are very fuzzy, but we hope you take this into consideration to make season 4 awesome for supports. Thanks.
