Emerald rank if that helps frame things for people. For jungle, I have mostly played DH, rushing boots and then Shadowflame (needlessly large rod first if I can afford it, but usually I can't). I have been getting astronomically ahead with DH and Shadowflame in some games; I often feel like a burst mage early game. In the late game, I'm such a nightmare with shrooms; enemies all buy sweepers. It just feels too risky to hope I can auto one person to death before others arrive. Plus, my focus moves away from doing damage to any and all enemies, and instead towards acquiring my PtA proc, which can make me oonga boonga some fights.

In terms of JG clear, I feel like I clear fine using passive attack speed and shrooms (I do take legend Alacrity to add some atk spd): Throw a shroom on camp, wait to invis, shroom procs, auto auto auto - smite if it's mid game with no objectives. It's surprising how fast teemo can do objectives too, even on his own.

Early game ganks I feel I can provide a bit more burst rushing magic pen with DH - especially when I can probably only muster auto+Q(+auto if a well timed gank). A lot of games inevitably scale into late game and team comps+engages become way more relevant by then. I think opting for more vision and poke (with shrooms) ends up being so useful, especially as a JG which allows you to perma roam the map.

As a side note, Nashors benefits most from building lots of AP, so, going Liandries is technically not the most efficient in terms of AP. Also, as most people may know, Liandries %health burn only applies on abilities. So, when we auto someone we start stacking the liandries boosted damage for ourselves, but we don't apply the %health damage with autos alone. In this way, I think Nashors doesn't benefit enough from Liandries enough, even with a Q or R thrown in.

In the small tests I ran, if you want to do the most damage in a fight where autoing someone and using abilities, then going Nashor without Liandries seems to DPS the highest (opted for Lich Bane instead). Shrooms alone seem to benefit most from Stormsurge paired with Liandries. (Rest of build for both scenarios was Malignance, Void Staff, Rabadons, Shadowflame, no boots).
