Why Offtank Urgot Is Better

I've been doing some math on Urgot's Q damage the other day, and as it turns out, its not entirely necessary to build Full AD in order to deal noticable damage. I discovered that his Q damage actually equals his total AD towards late game at Rank 3, which may help some players focus on ranking up Terror Capacitor/Corrosive Charge (whichever you tend to leave Rank 1 for a while) and have more benefits available from those spells. Considering Muramana is commonly used to boost his Q and auto damage output, an Offtank build can feature Iceborn Gauntlet for extra Capacitor value and Muramana boost damage.

<Table 1: Rough Offtank Value> 10 + (60 AD x 0.85) = 61 40 + (110 AD x 0.85) = 133 70 + (160 AD x 0.85) = 206 100 + (210 AD x 0.85) = 278 130 + (260 AD x 0.85) = 351

<Table 2: Rough ADC Value> 10 + (68 AD x 0.85) = 68 40 + (136 AD x 0.85) = 156 70 + (204 AD x 0.85) = 243 100 + (272 AD x 0.85) = 331 130 + (340 AD x 0.85) = 419

<<I use 340 AD to generalize AD Champion damage>>
