Return of Reckoning

So anybody knows a good addons for WE Bloodlust bar ? And if possible another addon like Pure or wsct with other themes would be great too. Last but no least can I do something so when I press Tab to switch to nearest Target but only chose enemy players and not their pets and turrets ? Thanks in advance !

Edit: Can someone explain me how macros work and write me any good macros like assisting the current war leader's target etc ?
