Most people I've talked to think that any of the Hunter runes are bad in 3s because there are only three unique champions to take down. But Riot did think of this and the two altars count as the 4th and 5th bounties. The text for the runes should reflect this to remove confusion.
A simple, low cost fix that would be very nice to have.

Tahngarthor1 votesIn Twisted Treeline, capturing each altar once counts as one of the five bounties. Thus, to get all 5, you takedown each enemy champion, capture the west altar, and capture the east altar.
The effects of the Hunter runes are permanent, they don't reset ever- each one grants you some sort of effect for each unique champion kill. As mentioned, since there are only three champions on twisted treeline, capturing the two altars was used to make up the deficit, making the these runes equally effective despite the lower player count.
The problem is the descriptions on the runes don't tell you this, and thus many players don't take these runes on twisted treeline because they think they will have reduced effectiveness.
