not a singed main (second favourite champ) but i do play him alot he's pretty much tied with leona on my second place.
I still build Roa/rylai core, with success. I think these items will become better on him with the ap ratio buffs and the double trail duration.
I'll agree ghost not being instant is bad for him but i think it's possible to play without RG (i play in low elo tho).
As a singed and teemo player i completely agree the mask just ruins these champions' day. idk who thought such a specific item was a good idea. it's fine against champs that spam spells but fucks DoT champs over.
Maybe they could make it less effective against Dot, like rylai's slow used to be less usefull FOR DoT.
Base mr should be reason enough to give some extra dmg to him, i'd personally wait for the rune update tho. I personally run Mpen runes on him and idk if that's still gonna be possible.
What i think they want to do with these ap ratio buffs is get him to function as an ap bruiser again, which i fully agree with. i don't like the ult nerfs tho idk why that's even needed.
His passive is 275 with base hp i think, while nice this is nothing compared to the power some champs get from it.
Maybe adding like regen to it might be nice already.
OR
Adding Movement speed to the passive. it would allow him to get some more MS to deal with dashes, for christ sake i never thought i'd feel slow on singed.
i would honestly like to see the passive he has now improved rather than getting rid of it.
Mega adhesive costs a stupid amount of mana early but i often level it at 3 anyway just incase, i barely use it early on tho. lowering mana cost or adding grounded while lowering the slow a tiny bit are ways to solve it imo.
I honestly wouldn't mind losing early game power for the lategame dream tho, but that's a personal preference.
Another issue i have is the upcoming change to abyssal mask, it seemed like a perfect item for champs like singed but now it's becoming a catalyst item, making it's passive useless with roa/RG/hextech ice canon thing.
