Vayne vs Jinx Vs Kog'maw

Vayne has mobility, peel, tank shredding, invisibility. Jinx has range, AoE Crits, lots of peel, mobility on kill or assist, AoE execution ult. Koggles has range, insane tank shredding, huge AoE slow, lots of poke.

IMO Jinx is best in teamfights, but Im not a good ADC.

Jinx does the most in teamfights; AoE 110% AD crits utterly massacre any fight if 2 people get close to each other.

Most damage is harder to calculate. Vayne has 50% AD next attack with Q, 60 (+8% max hp) true damage on W, and a 70 AD steroid on R. However, lategame using Q can actually cut Vayne's damage, as at higher attack speeds the animation is longer than the time to just do a normal attack. Jinx has a 140% AS steroid on Q OR a 110% AD range steroid, but that's it autoattack steroid wise. Kog'Maw has 30% AS on Q, resistance shred on Q, 6% max hp an auto on W, and consistent trinity procs on R. I'd say Vayne has the highest theoretical DPS, but Kog'Maw has much more range to use his high damage, and Jinx has much lower single target damage but has massive range and potential damage with Q AoE crits.

Vayne benefits greatly from a comp that can pick/isolate single targets for her to focus down. Jinx just snowballs a teamfight from one kill into an ace. Kog kills everything as long as you can protect him.

Vayne has very good single target damage and is better suited for dueling and skirmishing than the other two. She also has the best self peel of the three.

Jinx can potentially do a very large amount of AOE damage and a decent amount of single target as well. However, her only self peel requires that she gets a kill and she isn't cced at the time. Her single target damage is also very short ranged, while her AOE does less total damage if it only hits one target, but it has very long range.

Kog'maw has basically no self peel, but his steroid makes him do mixed %health damage at a very long range. If built right. he can also do decent burst damage with Tri force and his ultimate. If he has a team that will protect him, he will kill everything.

IMO, Jinx can potentially do more in teamfights, but a smart team can work around that. I believe Kog'maw has the most damage, but hes the least safe of the three. Vayne is more capable of taking care of herself than the other three, but still does very good single target damage.

Kog has the highest average damage of any ADC.

This is pretty consistently the case.

IMO Jinx is the best in team fights due to her AOE crits and her okay amount of utility for an ADC. Her passive's potential for quick repositioning if she's killing people helps.

Vayne's the best duelist and better at skirmishes.

Aces your entire team from 900 range while you all rush to dive him XD

Vayne is the best duelist of the three since she can get the jump on you with stealth and Condemn.

Jinx is probably the best all-around in a teamfight since she fits into just about any comp...

Kog'maw does the most damage overall and with a dedicated comp to support him will wreck absolutely everything.
