Remove the damage resistance of all treasure guardians so that it is more approachable for all players. correctly using melee mode will still reward experienced players with vastly better hp while not punishing new players as harshly. this will also result in better inter civ balance as melee resistance guardians punished melee only heroes too strongly.
make the Lakota killing strike and the Aztec swashbuckler instant. as melee only abilities on melee only units they are already quite punishing in regards to proper distancing, a slow animation delay harms them too much.
