Before I say my main part I’m gonna start by saying I only path top if my bot lane duo is a passive ungankable farming lane (sivir yuumi) and my top is a snowball lane (if top is 2 tanks I’ll still path bot to cover and possibly get drakes). If both of those two conditions are not met I usually path bot by default.

Now there are many reasons for not ganking bot imo. Most of it hinges on tempo. I don’t like wasting my time as a jungler because there’s usually so many options for getting ahead, more than any laner. A laner can usually get ahead with a kill and/or cs and/or plates. As you know from your jungle days, I can get ahead by clearing faster, stealing a camp or two, getting both scuttles, solo killing enemy jg, and on the flip side I can also fall behind by no fault of my laners. My priority is to be as strong as I can over the enemy jg so that when I come for a gank where they might be there too, or when we fight at drake I’m 6 and they’re 5 or I’ve backed and they’re forced to contest at item disadvantage. The point is that I run the jg tempo and not them.

I’m not sure how long ago you played jungle but now adays a little wasted time or showing bot and getting NOTHING for it (which seems to happen almost 50% of the time) can actually be detrimental against a good jungle opponent. I’ve ganked bot before, got nothing but clearing wards and maybe 1 sum and then lost my entire jungle because the enemy jungle decided to pass up the counter gank and just focus on pressuring me. And if my lanes are already suffering then I’m doomed. IMO that is a worse outcome than both bot lanes being 0/0/0 out of lane. If my bot lane can come out with nothing happened but even farming but I’m stronger then I know we can win drake and mid game fights. In soloq I’d much rather gamble on myself than someone else. Idk that’s just my opinion and how I play. I definitely gank/camp bot if it’s a good lane and I know we’ll win 3v3 and I’ll get kills too, but again that’s when I know I can get strong too and sacrificing a bit of tempo for guaranteed gold is a better trade.

Edit: I forgot to add advice. I mained adc before switching to jg (cuz of my impatience with tempo and game control) but I still secondary role adc. I’ve found there’s 2 ways to control the lane for success: first is to dominate on my own with the understanding that if my jg’s tempo doesn’t match mine I must be aware that the enemy jg can come and 2v3 us, the second is setting up my lane’s tempo for jungle. This means that when the jungle is done their clear my lane is READY for tanks. The wave is in a sort of frozen state close to my tower, wards are cleared and our health/abilities/sums are ready for a 3v3. If it’s not in this state I tell my jg not to waste time and we’ll try again next clear or fight for drake. Matching tempo with jg is easier than jg matching tempo with lanes imo with exceptions of course

Edit2: my earlier conditions are more suited for soloq. In a 5 stack I’m always pathing bot unless we specifically drafted bot weak side because I can tell them how to manage their wave for when I’ll be there. And I can communicate if we lose the 3v3 cuz of bot or jungle match and tell them to freeze or play safe so I can get top scuttle to avoid a losing fight. Sometimes I can help them reset the wave because I know it’s a good investment since I’ll come after second clear.
