Working on it :)

This is up to date. I edit and amend the information every two weeks (Or sooner, supposing something big happens).

I'd say it's probably still Darius, his kit just works so well for shutting down Singed, another good contender for the worst champ to fight is Fiora due to how tricky it is to deal with her W.

The notion of relying on players chasing Singed is super impractical and only really works in Iron-Silver, beyond that people know not to chase you. Having your Q as a zoning tool due to the slow is a lot more useful, and the way Q works is that if they're slowed, they're in the Q longer, and so take more damage.

Phase Rush still! My mistake on removing it!!!

I think to an extent this is true, maining Singed is a commitment and the learning curve is one of the steepest in the game. But if you put the effort into maining him then you can do some insane things no other champion would every dream of. Due to the struggle of maining Singed the community on the Discord, and to a lesser extent the Reddit, are lovely. You have to remember, if you enjoy playing Singed then you should play Singed, no matter what state he's in. I'm sure things will be better in the future and right now it's just a temporary rough spot

With great difficulty at the moment. You want to be playing around your passive a lot in this matchup- more specifically if he's using his W, you can more often than not run through him with passive to get away from it, or towards and out the side where it's more narrow.

The main issue is his Q and E though, with his E if he uses it at the further ranges you can't counter it, but if he's using it close to you, so long as you have the reaction speed, you can fling him and he E's you so you can at least create a bit of space and avoid his E AA Q combo. Building early armour helps here, but it's not to be relied on as of the new item changes, you mostly want to fight him in extended trades where he's forced to chase you if he wants to get AA's, if you just let him AA you freely then you're in for a terrible time, always be on the move and keeping your distance, let him come to you and run through your Q if he wants to fight, and save your E for disengaging him as opposed to using it to engage.

They do the same damage

Yes

This is a great question, I personally prefer future's market/time warp tonic when I'm running the inspiration tree as a secondary. I can fully see why minion demat might be seen as better in a lot of cases though, I base my judgement that future's market is better than minion demat on personal preference rather than reasoned out justification.

The way I see Singed is that he's not gold intensive, that is to say he gets all the items he needs after getting t2 boots, corr, and rylais (If we're talking about the bog-standard aftershock build), and having the future's market benefit helps give you a "get out of jail free" card because if you die early you're not limited by having less gold and can still get items even if you die/are forced to back at awkward timings. Minion demat can be great though because I also see Singed as being roam-intensive rather than lane-intensive and so having a rune which helps you shove waves in is always a happy sight.

How do you divide the minion demat stacks?
