Assigning roles in LoL in-houses — splitting primary and secondary fairly
Updated: September 7, 2026
In-house players always want overlapping roles. Here's how to collect a primary and a secondary role up front, and factor role preference into team-making, so you hear 'off-role again?' a lot less.
Overlapping roles are where arguments start
In an in-house, position causes more friction than the team split does. When five people want mid and there are two spots, every night turns into a standoff over who gives way. Even on evenly matched teams, someone stuck off-role has half the fun — and after a few of those they stop showing up.
So role assignment matters as much as balance. The key is not to settle 'who wants what' out loud every time, but to collect it in advance.
Collect a primary and a secondary role up front
If everyone insists on a single role, you can't make teams. Send people anywhere and resentment builds. The compromise is one primary and one secondary role. Most people have a role they're best at and a next-best they can handle.
- Primary: the role you're most confident in. Assigned first.
- Secondary: where you go when your primary is taken.
- Count low-demand roles like jungle and support generously, even as a secondary.
In ONNJ you can store primary and secondary roles on a summoner, and AI Balance factors that preference in when it makes teams. No need to ask every time.
Factor preference into the split
Lock positions first and the skill balance breaks; split on skill alone and positions get tangled. You have to satisfy both at once, and doing it by hand takes a while.
That's why ONNJ's AI Balance searches for a split holding skill and role preference together. When it can't put everyone on their primary, it spreads the off-role players so they don't pile onto one team. It isn't perfect, but 'why am I always off-role' drops sharply.

When it still doesn't line up
With exactly ten players and four wanting mid, someone has to go off-role. A few ways to handle it:
- Give priority on their primary this time to whoever went off-role last time.
- Offer a small perk — like first ban next game — to those who take off-role often.
- People who happily take jungle or support are an asset; thank them visibly.
Once records build up, you can see who has gone off-role how often. Using that as the basis for the next assignment makes it fair and cuts down on grievance.
