I propose an ideal change on Urgot's ult & W

As we all know, Urgot isn't in the big spotlight of all champions, since it has been looked down upon with clunky fighting style & has about the lowest winrates of all champions (u hapi now ? -_-). IMO, I can only see that his QE is pretty effective in most skirmishes, but the biggestt problem is his W shield & the passive of his ult. The shield looks pretty weak, even if Urgot has higher base shield strength than , it will scale really low in late game since 's shield scales 100% of her bonus AD, which seems stupid. And lastly, Urgot's defence buff on the ult isn't so useful to keep him sustain, similar if builds an insta- but still can be killed down easily (without his ult of course). So this is what I think I would like to change for Urgot's kit:

W- Terror Capacity

ACTIVE: Urgot charges up his capacitor to gain a shield that absorbs damage for up to 7 seconds. Shield strength change from 80 / 130 / 180 / 230 / 280 (+ 80% AP) to 60 / 120 / 180 / 240 / 300 (+5% bonus Mana)(+20% total AD)

**R- Hyper-Kinetic Position Reverser **

ACTIVE: Urgot targets an enemy champion and channels for 1 second, suppressing the target for the duration. If the channel completes, Urgot and the target will swap positions, the target will be slowed by 40% for 3 seconds. Urgot also gains bonus armor and magic resistance (armor & magic resist: 60 / 90 / 120) for 5 seconds, starting from the beginning of the channel time.

Urgot also gains 40% / 50% / 60% damage reduction for 9 / 12 / 15 seconds. For each basic attack he receives, the duration is decreased by 1 second. AoE effects reduces it by 0.5 secs. After the duration ends, he gains 5% movement speed & can pass through units for 3 seconds.

So please comment your thoughts on him, and forgive me if my numbers are kind of off. I'm lazy in doing the math.
