No it sucks and everyone except classic era players can see it clearly. Actually even blizzard admited that the tool sucks in their own post:
We had tank priests, healer rogues and other combos, ppl started to actually write in the notes what they want to do. Also levels are outdated there. Level bracket sucks because if you sign as tank for a dung, you were not able to be summoned by a stone because those levels did not match stone levels etc. I deleted my Deadmines quest because why should I bother when I am not summoned as tank and moved onto next spell cleaving dungeon.
