because counterpick counters.

talon doesn't really need a buff in his AD ratio or abilities, however, taking out mana and replacing it with energy would be a great idea and could probably be more skill based on when or how to use your abilities at the right time for burst/escapes of some sort.

Talon not bursty? Hahahaha you make the funnies

first of all I know how to play him, it's just that I think other assassins have more burst potential than him and can do it more smoothly.

and btw, enemies can only get hit twice from your ulti: once going out of talon and another going back.

I only compare their damage amplification, and it doesn't make sense that Swain has more than talon. Does swain really need more? Unless he's an assassin, which he isn't.

Could you explain this in a bit more detail? His burst potential is great and any 1 bonus AD you get increase your full burst by 4.5 damage, due to his great scalings. As for doing it smoothly - Talon burst is similar to any other assassin. You blink in, press QWER in a different order and people die. Or do you mean that his damage ratios per ability are somewhat uncomfortable, i.e. he is too reliant on his ult to do the damage?

It wasn't just winning lane, it was winning the game. I usually get fed as him mid (counterpick), but once fed I tend to carry games with him quite effectively. I can't think of another assassin that can carry that hard for a given amount of being fed.

I said not bursty ENOUGH. there's a difference between 1k burst and 650 burst. get it?

Swain damage amplification lasts for 4 seconds. Yes, its longer than Talons, but Talon does his damage instantly, while most of Swain's abilities are DoT. And his damage output cannot be compared to Talons. Even though % amplification maybe less, Talon is likely to get more damage from it just because he does more damage to begin with.
If Talon gets 4.5 damage from any 1 bonus AD, with amplification on max. rank, he will do 5.175 points of damage. Swain will only gain 2.6 more damage from any 1 AP he gets. And he has to wait for 4 seconds for this damage to go through. With amplification, he will get 3.12 damage. In addition, all of Talon damage benefit from amp. while damage on Tonment doesn't amplify itself.

level 18
200 bonus ad
enemy hp = 2500

talon = e----aa--------q--------------------w------------r
talon = 1.15(305.8 + 305.8 + 210 + 330 + 250 + 250 + 440 + 440) = 2911.34


2 clones after ulti:
zed = r----e---w----q-------aa---passive--r dmg
zed = 1.5(400 + 930 + 359.8 + 250) + 359.8 = 3269.5


evolved q, target is isolated:
khazix = e--- q--- 12% hp--w----r------aa-----r--------aa
khazix = 365 + 760 + 300 + 415 + 220 + 305.8 + 220 + 305.8 = 2891.6
which is less than talon's but khazix's ulti is more convenient since he has twice the chance to survive (in my opinion multiplte stealths is better than one slightly longer stealth) meaning twice chance to kill his target. If you want I can calculate other assassins' burst (surely for AP assassins they have more damage)
