They say it one shots, pentakill easy every game, it's op.
Why?
Whenever a change is proposed to Darius the counter argument is that his ult is op for doing true damage which warrants no buffs to him.
Why is his ult THAT hard for you to accept as a player?
Ignore the rest of his kit for this discussion, I'm talking specifically the ult.
TehNACHO6 votesIgnore the rest of his kit for this discussion, I'm talking specifically the ult.
See, like that you've removed a large chunk of why people don't like his ult, specifically the sorta weird interaction the two elements about Darius interact with each other. Not a fair discussion, methinks.
IsIsGankedParis1 votesThe reason I said ignore the rest of the kit is because people say it's only his ult that makes him op, his passive makes the ult do double damage but it STILL isn't that high of damage unless you go a TON of AD.
Yes the bleed is part of the ultimate but that's not my point, my point is that people firmly believe he shouldn't get buffed because his ult does true damage.
TehNACHO9 votesAhh, then let me explain exactly what makes Darius stupid, at least from my perspective. Mind me, I'm going to be using his whole kit in this explanation.
The problem with Darius is that his laning patterns too perfectly synergize with his ultimate, and unlike certain other ultimates in the game, it makes Darius close to hazardous levels of overwhelming in many scenarios.
See, Darius is designed like a straight lane bully; strong engage, good combo, good DPS, veeeeeeeerrrrrrrrrrry awkward team fight utility. Normally, this is perfectly fine. We have many champions that fill a similar niche, like Renekton or Pantheon, and they are perfectly balanced from what I've seen of the reds discussing the two champs (Pantheon's ability to fight dragon at level 2 unrelated to this discussion). So, the question comes, why does Darius apparently have so many people complaining about laning against him compared to these two champs?
Because Darius is too good at finishing the job. Pantheon comes very close, but 15% hp is arguably very low and you probably were going to die anyway. Darius on the other hand is a completely different monster. If a lane bully's job is to keep you below 50% health at essentially all stages during laning to keep you on edge, Darius can do this then immediately dunk someone to 0 with one more rotation of his abilities. Renekton has a nice and long combo using a lot of auto attacks to do correctly, meaning proper itemization, sitting in your own minions, or any cleanse/tenacity effects gives you a way to at least fight back against Renekton. Pantheon relies largely on his Q for his bullying presence, once again meaning proper itemization, or any good sustain effects, can keep you up against Pantheon. Darius though, it's significantly harder to counter him at all when you factor his ultimate with the rest of his kit. Built in Armor Pen and because his ultimate is true damage means that working around him through itemization is a non option, as health is hard to make an abundance of when on a low budget. He pulls people, rather than jumping on them, meaning minion manipulation is a non option. Because his bleed stacks up and does more damage with more stacks, not to mention unlocking the full strength of his ultimate, straight up fighting him is usually a non option. To top it off, because of the significant burst potential of his ultimate, sustain is a non option against him.
This is a huge part of why people complain about Darius' ultimate, in my opinion. It just rounds off the rest his lane bullying kit waaaaaaaaay too well. Out of context, if you look at his ultimate in isolation, you're right, it's not that insane. But when you look at in in context, when you see how it does waaaaaayyy too much for his kit, you'll notice why people complain about him.
Cale0172 votesThis guy gets it. I couldn't put it better myself.
You could cheese my nachos any day.
awkward cough
Cale0171 votesOhhhhhh, excellent point.
Cale0173 votesOops, my finger slipped and I hit W. 
hehehehehehehe
insaiyanbacca4 voteslol that satisfying moment when you spell shield someone's ult
Cale0172 votesDude. That summoner name. Kudos.
You know what's more satisfying? Skarner ulting a Darius who's in mid-dunk. I don't know if it was a glitch, and I don't care. I did it once and I forever remember that moment.
EllaRyu692 voteswell during his ultimate cast, he can be stopped by any hard CC so that's why people shouldn't complain lol
insaiyanbacca1 votesthanks.
yeah ive seen that happen before its funny, ive also seen a darius use zhonya's mid dunk so he was in the air and golden and when zhonya's ended he finished the dunk it looked really cool
PrinceOfStorms1 votesOops, my finger slipped and I hit W.
hehehehehehehe
If you are somehow immune to it (like if you Zhonya or Liss ult), Darius' ult goes on a 5 second cooldown, ready to smash your face in once your zhonya / liss ult ends.
What people dislike about it is that Darius' ult not only goes on a 5 second cooldown if it fails for whatever reason, but if it lands a kill its cooldown is reset, coupled with dealing a high amount of true damage, which cannot be mitigated.
If Noxian Guillotine didn't reset its CD upon landing a kill, I'm sure that people wouldn't find fault with it as much.
Cale0171 votesI don't know about you, but I've never seen a Darius last five more seconds after popping a Nocturne's spellshield and granting him enough attack speed to hit the cap for it. A Nocturne rarely needs more than 3 seconds to shred someone to pieces during the mid and late game if he's playing well.
Whether because I tear him to pieces before that ult comes back or not, I've never seen a Darius use his ult again after he pops it on my shield. I'm relatively certain that spellshields function differently than becoming untargetable, as the ult still registers as having hit it's target. It just had no effect due to the spellshield, instead of counting as hitting nothing like Zhonya's/Liss ult. I can't say for sure though.
Fadedpf2 votesGetting blood stacks is pretty hard in a team fight, he is a front liner which means adcs sit back and kite him, his e must be just right to actually secure a kill. Theres so many things that make Darius good and counterable. Why does no one cry and complain about 
or 
They have busted ults, busted damage, busted safety, and snowball hard. Fed Darius doesnt mean GG....
Cale0171 votesBuild MR and I guarantee Akali won't burst you down fast enough to keep your team from killing her for diving you. When she hides in her shroud to give herself a few moments' reprieve, unload every AoE and skillshot you have into it and she'll die, especially now that it doesn't buff her resistances.
Build Zhonya's or stack resistances and I guarantee that Zed won't do it either. Hell, you can build a QSS/Mercurial Scimitar if you're an AD champ and completely negate the bonus damage on his ult while using those few seconds before he shadows onto you to to jump, run, dash, or flash back to the middle of your team so that even if he gets you, someone else is going to lock him down and he won't get out alive.
A fed Darius in many cases DOES mean GG because he can push insanely hard, usually ends up being able to 2 or 3v1, and can kill someone fast enough to where him being a frontliner doesn't matter because he's just carving his way to your back line. It takes a team to stop a fed Darius, the same as it takes a team to stop a fed assassin.
Provengreil1 votesI've never seen it happen, he always seems to be drained of mana after 2 or 3, even he's wrecking in the game.
