I think the tier levels for ZS raid bosses need to be changed. I have opened 8 bosses so far and the top tier Levels 3550+ fills up just about instantly the 2nd tier Levels 2001 - 3549 fills up eventually and the 3rd tier Levels 0 - 2000 I am lucky if i get a few to join. Its my opinion that they should probably be changed too low tier 0-3000 mid tier 3001-4999 and top tier 5000+. Can you please take a look at this and adjust accordingly.
at the rate of the levels are now I think 0 to 4K then 4001 to 7k with the rest being 7001K upward. The ratio should match the player levels. IMO
