Please consider doing some changes to the practice tool so as to make it a better, more accurate instrument for what really happens in the game. Especially regarding champions that deal HP-based damage (e.g., Vayne, Vi, Kaisa, etc.), since the dummies have such high amounts of HP, the tool can lead you to believe in false builds with items that scale off HP. Please try and make the HP, armor, MR, etc. of dummies adjustable so we can have a better understanding of what works better at what stage of the game.
