[PS4]{WAR/MRD} - A Few Questions

[UlricCraft]

Hey,

I recently started playing marauder and I've got a few basic questions...
I'm level 26 and have access to these skills.

1. What is the best basic single-target low-level enmity generating rotation?
   
   People have told me: {Skull Sunder} only. Others have said {Heavy Swing} - {Skull Sunder} combo is better. Both seem to keep me holding aggro well enough. Often I'm scared to use {Heavy Swing} as I fear it won't give me the additional enmity needed to hold for the following 6 seconds.
   
   
2. Does {Tomahawk} grant more enmity than {Skull Sunder}?
   
   Is there a chart showing which skills produce the most enmity, or is it purely based on damage dealt coupled with a modifier for certain skills with the additional effect: Increased Enmity?
   
3. What method do you use to monitor enmity on the mobs?
   
   Do you have any special hud layout or is it simply rotate through the mobs occasionally looking at this:
   
   

PS4 USER SPECIFIC

1. How do you tag mobs with <1> <2> <3> <4>?
   
   Are there decent macros?
   Do you just put the icon on your hotbar and manually click them?

Thanks in advance!
