For me, it's gotta be toplane being an island.
I left around the time when this trend started dying and coming back now, they've really gone all the way through with it.
Overall, I begrudgingly have to agree with this change. League is a teamgame and especially for competitive play it's great that it's so interactive now.
Can't help being nostalgic about it though. It was you and one dude, minding your own business and not having a care in the world. If you got a kill it didn't really matter too much, you could always come back since your KDA didn't really affect your team until much later, same way the other way around. Oh yeah, also not having to worry about junglers because ganking it would just be so goddamn worthless.
What about you guys?
