As the rules stand, in 5 Leagues you resolve close combats as soon as you have finished a move.
I have been testing out finishing all moves for the Phase, then resolving combats.
This allows ganging up a bit more, as well as making positioning a bit more important and tactical (which I think is a good thing).
Give it a spin and let me know if you think it'd be a good update.
Amend the Proximity rule on page 21 to read:
If a figure moves within 1” of an opposing figure, they engage in Melee combat.
At the end of the current Phase, all Melees are resolved. In the Quick or Slow action Phases, the player may resolve Melees in any order desired.
In the Normal or Monster Phases, resolve Melees from left to right.
