2 Things first:
- Kai'sa got buffed by 25 Range, from 500 to 525. Caitlyn also has 650 Range.
- Yes, 350 Range is definetly large enough to escape most of the laners attacks.
- I personaly kinda like The Djinns suggestion but i am totaly against to give him total melee advantages all the time rather as never or part time (during w) and here is why:
Your caitlyn comparison is wrong on diffrent sides. That "enough distance" is definetly not the point most times considering botlane is a 2v2 lane there most times at least 2 champions are range (adcs) and supports are either range vs range, melee vs melee or range vs melee. The whole botlane dynamic is totaly diffrent as on toplane. Farthermore do both classes, adcs and supports, often have high range abilitys much diffrent to toplane.
You gave the exampel with Darius e which has a range of 535. Well Alistar w has a range of 650. Braum Ult has a 1250 Range. Taric e 575, lowest range engage (works also as disengage) but on 2 champions. Blitzcrank Ult alone has 600 Range. And theses were just some of the Melee Supports. Ofcourse the Range of the range supports and adcs is mostly consistent higher. Lowrange adcs have mobility, Rangesupports have often movementspeed boni in their kit and from mobiboots. There is often time to trade with Caitlyn.
I want to compare how both, Urot and Caitlyn, can deal with engages cause both have their e. Still what did you say again, not while you complained about how easy champs like Darius can enage but farther down:
He can get up close and personal with an enemy champ and do just fine...Think about it, if you tried to engage on him, he wouldn't care, unlike adcs he thrives in close up fights... The flip-side for adcs is that with their long auto ranges, they can't handle up close and personal fights as most lack innate bulk and major cc in their kit. Urgot does not suffer from this being that he has a slow and a displacement, along with the hardest cc to deal with strapped onto his ult: Death.
So you say champs like Darius can engage him very easy but at the same time that he doesn't care much about engages cause he loves that and is tanky and has a good kit. So what should i believe? I believe your second part is true but lets just assume that wouldn't be, that he is squishy and fears darius: Well, if Darius hooks him Urgot can easily e away again. If a renekton dashes threw urgot, urgot just e away and even throws renekton back behind him again and stuns him briefly. After that he can use his q or ult to slow them.
Well that was easy but what if the second part is also true? Lets discuss this later.
2 Points Urgots enemies have to deal with much harder as caitlyns enemies: Not much healing/protection and minionaggro plus creepblock. On Botlane the Heal/shieldsupports give some defence vs caitlyns autos. Even most melee supports have some protection beside enages (exception leona and nunu), but even these 2 can heal up with relic shield tiemline.
If Botlane trades they can clear waves easy with2 together and they also can tank them easier with 2. Rangechamps (so adcs always) can easier escape the aggro and not stay in creppblock. Botlanebrushes also are far bigger and with that easier to reach for geting off aggro, but mostly it is enough to just walk back a bit.
Toplane has no shielding or ehaling support. Also they clear waves slower, need to tank creeps alone and stay than in the middle of a creepwave there minionblock can happen. Yes Urgots thick model and 350 range doesn't negate all of the melee downsides but still he can far easier poke and just step away to reset minionaggro again. He also has w as a shield to tank up miniondamage too and it gives him the ghost effect aka no creepblock,
Now to continue whre we stopped before at what happens if Urgot realy likes to fight even close. We have Darius as a Juggernaut and Renekton as a Diver. What happens if Darius or Renekton engages succesfuly with ew and Urgot tries not to run away? Well he would put on his w, with good reactions before they use their w, and try to mark them with q, also maybe clearing already some minions. With w urgot is already tankier and tanks the minions far easier. Sure the 2 exampels Darius and Renekton can heal up with their q, but if Urgot doesn't run away and stays close Darius will neither apply passive or heal himself with q on Urgot and can just try to clear some minions and to heal on them himself up. Renekton has a problem on how to use his e recast: Will he dash threw Urgot if the first was just to come in range for the stun? Than he would intentionaly throw himself for more damage of Urgots passive while Urgot still has e up. If Renekton just does ewq with some autos threw the autoattackresets and than e away again, he will have nothing up for some time giving Urgot the posibility to autoattack him down and go for the q slow and e follow while, like i said before, taking not much damage from minions and no minion block cause w.
So not only can win Urgot vs Divers and Juggernauts, he also has the posibility to escape them if he fears fights and has no guts to use his true potential.
And Urgot also not builds squishy. He builds like a Juggernaut if not even more tankier. Even with weaker effects for range he still goes currently Black Cleaver and Frozen Mallet for a good amount of Ad, healht, additional Mobility and additional slows which strenghtens his bully potential. Only item he can could want but currently can't get is Steraks which would him make far tankier as he already is over the other "Bruisers". Like if a Darius goes Steraks he has a shield like Urgot. If Urgot could go Steraks and it would be usable all time he would have 2 shields all time. Urgot would be as tanky as a tank while doing far more damage AND being range.
Now here is why i like The Djinns idea kinda: If urgot just counts during w as melee, his w tradeoffs can balance him during that stance. W is not always up and while it is up just not focus Urgot so Steraks doesn't activate. ofcourse you can not always do that but having to deal with w steraks while they add each other gives Urgot a good strong point to fight. But if both falls down he is even more an easier target (cause steraks probably repalced a full tankitem).
W slows Urgot but also gives him slow resist. Now w negative effects are strongest in the early game but even if Phage would Speed Urgot more up during w cause he counts as a Melee and the Mallet would slow far more, Urgot being self slowed cause his w makes it kinda bet cause the phaemovementspeed even on melee is not as much as w slows him.
Now here are my 2 concerns: With Swiftnessboots Urgot even weakens his selfslow and the +60ms and the phagebonus would make Urgot w nearly make no tradeoffs. Plus the slow on malles which is effectivly doubled. Like enemies have a much harder time to stay close to urgot so he can kite far better (nice "melee" he would be) but also they can't as easy escape his w range which leads to them geting far more damage from Urgot, even if he didn't mark them cause they just stay longer in the closest range. At least q slow on urgot is dodgeable and just for 0.6s, but in a fight with no minions near Urgot w is an autoslow and 40% would be much.
Well the first part could at least be solved with increasing the movementspeed punish of w or/and make swiftness boots no longer effect selfslows, but the frozen mallet effect is hard and just by increasing the w selfslow i don't realy know if that would be ok to deal with. After all it effects even Divers who want just to pass urgot and attack the backline, they would have a much harder time to reach that. But nerfing Mallet could than just be made for all melees.
Well, Riot mentioned they want to rework Mallet entirly but not sure if that realy happens, when and how it will look, especialy melee/range diffrences.
