Hello, add this in your fightclass like:
 
RunMacroText("/petattack");
RunMacroText("/cast Hunter's Mark(Rank 2)");
RunMacroText("/cast Berserking(Racial)");
RunMacroText("/cast Rapid Fire");
	with spell settings "Not spell is lua script" > True and "Once per target" > True (and add distance condition)
 
	 
 
	But, you can also add all spells normally in your fightclass
