New Keystone: JuggerCrutch
For every second in combat with champions (DoT exception. Cuz Darius), gain 1 stack of JuggerCrutch (stacks up to 4)
Each stack of Juggercrutch gives:
Adaptive Base AD/BonusAP: + 1-6 (increases every 2 lvls, caps at lvl 12)
Bonus MS: + 1-9 (increases every 2 lvls up to lv 10)
At 4 stacks (4 sec in combat w/ champs):
If melee, become "Belligerent"
Gain 10 +(1% Health from items ) Adaptive Bonus AD/AP
Doesn't include bonus health from passives or actives
Don't know which tree it should be in, but thinking resolve.
Bonus MS helps with sticking to targets, which is what Juggernauts struggle with. Tenactiy would also help, but runes for those already exist. Juggernauts would love the speedboost from phase rush, but most juggernauts can't land 3 spells within a super short time frame to trigger it. Ideally, juggernauts shouldn't have an issue staying in combat. Because the movement speed builds up in combat, it encourages users to stay in combat rather than using it as a sudden ms rush to escape like phase rush is sometimes used for.
I was originally going to set the scaling to increase every 3 levels, but I feel games end too fast at the current moment for that. Additionally, most juggernauts fall off lategame.
Skirmishers won't really like the keystone a lot because 34 bonus AD (no true AP skirmishers yet) as a reward for staying in combat for 4 seconds really doesn't do much for any of them. The movement speed is nice, but skirmishers tend to not have issues sticking to targets, so it's superfluous.
By making the bonus stats only partially scale with health doesn't fully disincentivize experimentation, but makes the keystone a lot better if you're actually building tank items.
Obviously, making the stats scale in combat makes the keystone not super good for bursty champs. By limiting the combat to champions, the keystone isn't literally just giving free stats.
Because the stats are in-combat rather than based on autoattacks like fervor, the keystone is open to more than just aa-reliant champs.
The stacks would build up as Juggernauts are being poked; I don't know if that part is fair because poking and kiting are supposed to be a Juggernaut's weakness, but it's also what keeps most of them trash tier. Could be fixed by changing "in combat with champions" to "Dealing dmg to champions (excluding DoT)"
The amount of bonus AD received from the health scaling is 0-1 Adaptive when champs first enter lane (Doran start = .8) , about 2 AD after 1st back (~ 5 min) with ruby crystal+doran, about 4 AD at lvl 8ish (1st full item complete, ~ 9 min), 8 AD at lvl 12ish (2 items, ~15 min), 12 AD at lvl 14( 3 items, ~20 min)
So, this should amount to:
|Level------- |Stacks Adaptive Bonus| --- |Belligerent Adaptive Bonus| --------- |Bonus MS at 4 Stacks|
|-
|1| 4| |10+1| |4|
|2| 4| |10+1| |4|
|3| 8| |10+1| |8|
|4| 8| |10+2| |8|
|5| 12| |10+2| |8|
|6| 12| |10+2| |12|
|7| 16| |10+2| |12|
|8| 16| |10+2| |16|
|9| 20| |10+4| |16|
|10| 20| |10+4| |20|
|11| 24| |10+5| |20|
|12| 24| |10+8| |20|
|13| 24| |10+9| |20|
|14| 24| |10+10| |20|
|15| 24| |10+10| |20|
|16| 24| |10+13| |20|
|17| 24| |10+17| |20|
|18| 24| |10+varies| |20|
So it winds up being fervor with slightly less AD compensated by ms that incentives tanky builds.
The restrictions on bonus health being from item stats prevent cinderhulk from warping it, but also prevents health stacking from abilities being a problem (Sion, Cho in particular).
I don't think pure tanks will want these stats on them, but I'm not a tank player.
The AD/AP stat splits are for future Juggernauts and Mordekaiser, though I don't think Morde would like this keystone. I don't really play morde much, though. The only concern with leaving Adaptive Ap are the tank AP assassins (Fizz and Ekko), because there's no "base AP" stat. Making the stats only AD might be necessary because of that.
You don't need conqueror to botlane. Morde and Wuk (Wuk's more of an assassin though) are examples. Conqueror is just too good of an option on many champs to pass up (compared to alternatives). For example: Conqueror outshines anything else Yas can get; Conqueror outshines anything else Irelia can get. Apparantly people really like conqueror on renekton and darius as well for both bot AND top. But they don't need conqueror to be able to go bot. They don't need true damage. Darius shouldn't even be getting conqueror with natural % armor pen.
