Ignite brings an extra 70 true damage at lvl 1 combine that with your passive thats 142 true damage at lvl 1. Twitch's true damage is like 1/4 of his total output and ignite increases your early game damage deceptively preferable applying it when you hit 4 stacks and it will force an enemy to retreat or give you a kill early game. It isn't mandatory to take ignite on you or the support but I feel that Twitch's true damage is what throws people off and I want to reinforce aka more/less exploit other people's lack of experience vs Twitch's true damage by packing ignite.

You have to think about who the enemies are playing as and what your support is playing.

You can expect someone like Sona for poke lane and her Q has 700 range, true that she will run herself OOM if she does it too much but if she can get you to pop a health pot then it would be worth it. She can keep it up for a while too. Lulu is another one that I find that can poke quite well. Then what would other adcs do against this? Corki can use his Q to counter the pokes as that range is 600 with a 250 radius aka reaches 850 out ranging Sona's Q and slightly less than Lulu's Q. Twitch can use W, 950 range, to engage on the support but you would expect to get close and maybe do one or two attacks before you have to disengage as the enemy adc would intervene and with 4 stacks and expunge then you should severely would the Sona if doesn't E away. Lulu would Q then polymorph you and get one auto off before retreating. You take free harrass and get nothing done other than a small amount of true damage done.

If the enemy is going murder lane then you can expect Leona or Blitz then you have to really the skillshots. Think about what the other adc can do in this situation. Vayne can condemn Blitz or Leona after the stun/knockup wears off. The adcs that you mentioned can mostly disenage from a good Leona. Draven, if he reacts fast enough, should be able to use his E to dislodge Leona's E(I think it works) and follow up with a spinning axe or two. MF would probably flash out if she doesn't think she can duel. If she does duel then she would position herself with regards to the enemy adc and Q the support and get the bonus damage on the adc. What can Twitch do in this situation? Stealth to safety? Not before taking one or two more shots.

But these situations can be turned around if you have the right support. That is the thing though I don't know what kind of support works with Twitch. I expect Leona but she kind of works with almost everyone.

Then there is the adc you have to deal with. Draven will out muscle you early game. Caitlyn will abuse her range on you. MF is tankier than Twitch(base stats wise). Varus slightly out ranges Twitch and has damage on hit that stacks for extra burst damage. Vayne will straight up out dps you(Auto attack, tumble, condemn, procs true damage) but eats up more mana done in like 2-3 seconds faster and more upfront than your true damage. Trist can jump on you or away from you when you try to engage on her not to mention that the longer you wait to engage on her the harder it becomes as she starts out ranging you slightly as soon as she hits 2 aka starts auto attack animation on you before you get a chance to start your animation.
