I expounded on to why it would be a shit role in that team, and why it is a shit role for relative rookies to be thrown into, especially given that there are vastly more experienced players around you who would possibly (probably) be better suited to making these kinds of decisions after playing for literal decades.
Even if you are naturally inclined, IGLing takes a long ass time to get good at. It helps massively to be in a team of peers though, or at least a team where your insight or experience in the game is considered roughly equal to their own by most/all members of the team.
Lekr0 should've been played as more of a star role or aggro entry, not supportive IGL to BoT_RiGhT. Problem with nip is that it has been dragged along pretending that the two older guys should still be in star player roles, when their time had come and gone.
