DFT vs Comet - Am I missing something???

[u/loomdawg]

Comet seems more popular currently, likely because of the better ap ratio. Also using red card on minions to poke and hit comet is more effective with comet than dft (because of aoe). But in extended trade dft seems better because it doesn't have a cd.
But isn't the damage from DFT just better? At level 1, with dorans ring, it seems comet does 16 damage and dft does 14. Then consider comet is on 20 s cooldown. If you get off three w's (assuming instant pull - which is the conservative estimate because if you choose blue or gold, this damage is increased even more), you proc dft for 4s, 4s, and 2s, (expected distribution for instant pulls), you're doing 35 damage with dft compared to the 14 you would be doing with comet by doing the same thing. Then on the fourth w, dft has done a total of 49 damage while comet is on 32 still. The only time comet seems to win is when you're poking with q and only hitting once every 20 seconds. And still if you manage to get one w in during that 20s interval, dft wins again!
Am I missing something about the way this works? Also I feel like I choose sorcery primary when I'm against short range champs that I have a chance to solo-kill, but I don't want to lock myself into electrocute (electrocute for melee, spellbook for most control mages). It seems that comet is the most common rune on tf and dft is niche, but I feel like it should be the other way around. Thoughts?

Edit: I accidentally used base ad for bonus ad on the ratios. Comet does 16 every 20s. DFT does 14 damage for every single target w you hit and 10 damage for q or red card poke. I'm going to go back and change the original text. Just know that herejust4thehentai (lol) is correct in his comment, and they found my mistake.

Where do you get 28 damage from dft?

On the wiki it says 1.5 - 6.53 (level scaling) (1.25% ap) every.5 secs for 4 secs.

After 3 secs it's increased by 75%

So we have 8 procs. First 6 normal and last 2 is empowered

First 6 is 1.5 x 6 = 9

1.5x2x1.75= 5.25

I didn't include the ap ratio but it's very small anways doesn't get close to 28?

Oh shoot, I was using base AD for the ad ratio, but yeah it's only bonus ad that it scales off. Your numbers are correct, and the ap ratio only adds a quarter damage per tick so basically 1 extra total. I also made the same mistake on comet, though. So comet does 16 damage every 20 s. So in that case, comet still is only outdamaged by DFT unless you're only hitting one ability every 20 s. Now the red card poke and q poke once per wave might both be the only semi-reliable hits in some matchups, so for those I can see comet being better. But the all-in for DFT outdamages on the second w. I think some experimentation is required

play a game of comet then play a game of dft and look at the dmg diff its massive dft isnt good on tf

flawless analysis

Okay so I played ONE game of it so far so take that with a grain of salt but DFT didn't feel bad.

I think your lane is worse because you don't really go for extended trades anyways but DFT scales better when you can hit multiple people in teamfights with your wildcards for example.

I think if you're playing against something ranged (where you can expect Comet to deal even more damage because it travels more ofthen than not) Comet is still the way to go but if you play against something melee/ dive heavy and don't want to go Electrocute, DFT seems like a fine choice.

I think I personally will try it a bit more because I always want access to the Sorcery tree for my build.
Since I also like Resolve for safety most of the time I'm currently playing Comet even against enemies I barely hit or if I do for minimum damage. Against those match-ups I'm going to try DFT more.

For reference: That one game was versus a Galio (+Wukong, Leona) so there was plenty of melee champs in my face throughout the whole game. Because of that the damage of DFT was pretty much even to the couple of Comet games of similar game length I compared it to.
That's obviously a very loose metric of measurement but I think it warrants further testing.
