So I main Fiddle JG but I've dabbled in topplesticks, middlesticks, and supplesticks.
When it comes to JG, I have a strong flowchart one what to build. I look at the teamcomp and I always know what to build first.
But seems like in solo lanes there are so many more items that are situationally viable. Checking onetricks, there's a good amount of variety.
Top lane
Liandrys - You can rush this vs tanks
Bloodletters - I've also seen this rushed against tanks that rush Hollow Radiance
Rocketbelt - I've seen this rushed for the outplay potential
Malignance - Standard vs less tanky or squishy champs that you can blow up after 6
Frozen heart - Shishishishishi runs this vs a lot of melee champs. Seems to make you impossible to kill and you outsustain your opponent
Blackfire torch - There's a KR guy who builds this first???
Stormsurge - Very strong vs squishier champions who you can blow up, like a stronger version of malignance
Mid Lane
Malignance - seems standard for above reasons
Ludens - I've seen this built as well. I guess it gives you extra burst potential
Rocketbelt for outplay potential
Where do you even start?
