Bane + Legion Commander

Why this works

Setting up a Duel with Fiend's Grip seems like the obvious play, but it can be surprisingly awkward. Bane is a sitting duck while channeling his ultimate, making him an easy target for the enemy team while Legion Commander is occupied. The spells end up being redundant; the target is double-stunned while the rest of their team is free to turn the fight. The more effective play is often for Legion to find her own Duel initiation, freeing Bane up to use Fiend's Grip or Nightmare on a different, more threatening enemy hero. This requires a level of coordination and positioning that isn't always there.

Across the course of a game, this means the lane's success is very situational. If they can isolate a single hero, the lockdown from Bane can help secure the Duel damage for Legion Commander. However, prepared enemies will focus Bane the second he starts channeling, knowing he's immobile and vulnerable. They can also use strong defensive saves on the Duel target, as Bane doesn't offer much burst damage to help finish the job quickly. The pairing isn't actively bad, but the heroes don't consistently solve each other's core problems.
