Wouldn't Descent Champs to better at a 45-50mins duration?

In its current format DC is way too short and ez imo and the deciding factor of who wins is more about who full clears every zone and has lucky density/champ packs.

If the format is shorter, I think it will be much more entertaining, fast paced and you'd actually have to take risks if you wanna win. Cuz obviously the best XP is in merciless Halls.
One would have to choose whether to rush there faster and try to get as much XP there risking dying or playing it more safer.

A shorter race would mean even more reliance on lucky packs. As you'd be racing ahead to mericless levels, and you best hope to hit enough blue packs to not be under-leveled.

How bout instead of ranking players by xp totals, theyre ranked according to the speed at which they kill the final boss? Essentially turning DC into a time attack mode (with actual racing!).

That or just add an endless ledge type zone after the final boss.
