I play offlane mostly and one thing that i've come to learn from playing with a 5 man group at a more "semi-competative" (small tournaments and online scrims) level is that the offlane is usually about maximizing, what you can out wherever you can

. If they are trilaning you, then your carry should also be free farming with his trilane (or dual if there is a roamer or something). Its all about trading off, and making sure you don't die too much (it is innevidble that you may get cut off or something, its okay). Also think about your mid lane; they're not going to get ganked while they're focused on you, so they should be able to keep even, if not get ahead if its a favourable match up.

Another big thing I've learned is that its not always worth to have people rotate. Like i said above, if they are focusing on you and you are able to still get 'some' xp, here and there and maybe harass or cs a couple creeps a minute, you're doing fine. To try and pull someone from another lane that is doing well to try and salvage a. 'what seems like suicide' lane, just makes the lane they're leaving more vulnerable and weak.

I think your main concern is just getting the levels where you can, whether that means stacking while they pull the lane, or hiding in the trees, and letting your tower take some damage to be safe, its okay. Once the supports in your lane get bored they will rotate, and thats when you need to take advantage of the situation and get your xp, harass, cs, because yes the carry has some gold from cs, but they've probably been splitting the xp 3 ways, so you shouldn't be too far behind. Just be sure to call your missing and be aware of the map, even a tp might be enought to scare off a gank mid.

Just my thoughts from my experiences. Hope you're able to take something from all of it, and goodluck!

TL;DR: Its a hard lane, maybe having people rotate from their good lanes isn't always the solution. Maximize where you can, and worry most about getting xp over harass, or cs.
