Suggestion - add a 1v1 Vampiric duel mode:
- Players would start fully overhealed
- Any damage dealt would be transformed into HP restored for the attacker (1:1 ratio)
- The round would start after 3-5 seconds, allowing both players to reach the center of the map
- The round ends and resets when a player dies
This is something Quake had for a very long time (ADHD mode) and it promotes raw movement and prolonged aim duels. The overheal and HP "lifesteal" are exactly like described in the points above, but the other 2 may be tailored more toward MGE and balancing as quake players have more of a gentleman's agreement on when they should start their ADHD duel.
It would probably work best for hitscan i.e. scout v scout, but would be interesting to see how it works for other weapons (soldier and demo).
