What function does Kog'maw provide that you don't get from another marksmen that is also safer and doesn't require late game to come online? There's just not enough peel in the world to make up for his immobility, so why pick him?
Leti the Yeti3 votesur the closest thing to a siege catapult thats not ziggs and also an adc
ScurvyNave3 votesKog'maw is the ultimate Anti Tank ADC with a long range nuke. His W is what makes him unique. Plus free Attack Speed and % health damage make him stronger in late game than other carries that perform similar roles to him.
Plus he's one of the few arc's who has a skill that doesn't cost mana
Also his passive is so fun to kill people with :)
If you look at the other three late game carries and compare them to log you'll see they all have different roles/styles of play
: A tank shredded, nuke dropping, range steroid tower destroyer who can poke from behind his team. A "living artillery" so to speak.
: A stealthy assassin adc with short range but poison effects and a team fight based ultimate.
: A un-escapable juking machine with tank shred on her W but also short range. Finishes off targets while running them down
: A slower scaling AD with the longest range in game. quick attack speed with a reset for escapes and chases. Can hit towers and objectives from far away like Kog but is more vulnerable early game and doesn't shred tanks as easily.
Hope this helps explain Kog'maw's role (Not sure what early game champs do the same as him so feel free to point any out)
Maximum Zilean2 votesHe is more team dependant, but scales the hardest out of the late game carries.
The other 3 have a reaction to assassins and dive happy fighters.
Can rocket jump away and ult.
Has her E, and can outduel some assassins.
Has his stealth. (harder to escape with after nerfs though)
, Only thing he can really do against them is "Prey your team can peel". Not a good solo que pick in this regard.
Poorly Dressed2 votesI think he is a great champion with fun mechanics (especially if you can get revenge with your passive) and his range is just absurd! On top of that you basically get 2 champions because he works as AP midlaner as well :) His ult feels rewarding if you can land it across the screen and shredding tanks is his speciality! It's one of the few champs where i feel comfortable going straight against tanks where other champs might fail! Also i don't like the whole mobility creep, so Kog is the a very good pick in that regard! And he has awesome skins too :D
cloudbreaker991 votesHe does more damage than other adcs lategame, but other than that hes pretty mediocre in solo queue
TehNACHO1 votesFunction: When he does come online, he trounces so many other ADCs in raw damage output, especially against tanks.
He's a tank buster, and when he comes online, oh dear god he is good at it. This is the niche Kog'Maw fills that only one other ADC really competes with him in , and when you consider what the ADC's job on a balanced team is in the first place, this is why Kog'Maw is a valuable pick if you're willing to work around his weaknesses.

is always banned
xJLx MCHammer1 votesHis range is absurd, his mix dmg that shreds tanks, and huge scaling
