Yes just, rifles isnt that good in hum vs hum. AOE + knights + casters (breakers )> rifles + casters.
Alos vs elf , dont mass them without some casters like breakers/sorcs/priests if the other goes mass archers and bears or dryads. You can use mortars vs mass hunts and mass dryads which works.
Vs UD and Orc you can own with rifles and casters but if he makes spiders then you'd better try knights or just foomten with defend ,casters, several mortars + AOE
