i had someone tell me that it would block the screen and that isnt true. Check out my character highrohan on stormrage's UI. I used it to level through pvp against the highest encanta spell godry. The action bar is on the bottom right then a few buttons above to the right for ease. Its easy to set up with bartender. You just change the scale on the action bar to 2 the highest and place the bars to the right bottom of the charcter you can have up to two bars without blocking the screen. Remember to use your stuns and ccs either as a click through gladiator or on click bar, and your high cooldown spells.
Hey i would like to tell you about a addon i made using bartender and i really think its worth your time. I took bartender created a action bar to the side
of the charcter (right) turned the size up all the way and put high cooldown spells on the action bar. I call it click bar. You can now click spells with ease and without strain. Tell me what you think about it. I play highlord thats my blizzard id i have charcters on stormrage with similar names highseerxand is one of them check it out and tell me what you think.
