You're welcome
And I can understand where your coming from with the numbers debate. If this idea were to be adopted, I could be for "no pure numbers" if they threw some interesting checks into the battles. And I think there should be one for every 10 ilevels, which each challenge progressively getting tougher. Not just in pure output, but in mechanics as well.
ILevel 40 Challenge! : 3 groups of 2 mobs each. Think treasure map.
ILevel 50 Challenge! : Fighting a boss with differing AOE patterns on the floor to dodge
ILevel 60 Challenge! : Boss fight. At spots throughout the fights 2-4 adds (of varying HP pools) spawn on outer edge and walk towards the middle (think crawlers from PS). DPS checks to kill adds before they reach the middle or cause insta-wipe.
So on and so forth. If the hests themselves brought a little bit of flavor to the fights with some interesting things we need to do, (this part is important)
which simulate real things asked of us in endgame content I think this would be pretty valuable even without pure DPS numbers. Higher levels can teach you how to prioritize mobility, when pushing phases is important, and other small nuances of fights. Pre-ilvl50 hests could focus on helping you maximize your rotation, not by telling you or holding your hand, but by failure of the hest itself.
