Once Again, the PBE shows that the balance team has no idea what they're doing.
You actually are buffing Eve's damage back up (LOL), you are nerfing GP's Q mana cost and his barrel timers when GP is absolutely fine after the Klepto nerfs dropped his winrate back down to 51% in Plat+. And a bunch of other meaningless nerfs/buffs without addressing ADC's like Tristana or Varus or their incredibly cheap build paths. Once the balance team finally pulls their collective heads out of their asses and nerfs the cheap costs of Phantom Dancer, Shiv, RFC, etc, those nerfs will directly hit GP as well who also builds crit damage. Like almost every other champion, GP benefits greatly from Stopwatch to deter the enemy jungler and opposing toplaner from diving him. IN SUMMARY: get rid of stopwatch, increase cost for ADC build path, and nerf Tristana's AS buff on her Q and her base damage on R at rank 1. (Varus might not need addressed).
