You're talking about splitting the queue even more which is adding more to the problem. The issue isn't that people can't get i80 (like... it's stupid how accessible it is), it's the lack of interest in Wolves' Den. The way morale is now, I think, is far better than it was before. Morale was a broken stat that created a wider gear-gap than anything in this game.

Wolves' Den becoming popular again won't ruin Frontlines, especially if they eventually decide to get rid of GC restriction. Why? Because all the excess players from whatever GC that aren't getting in every match will then be pooled in to fill in the blanks where needed.

An "adventurer-in-need" would be very good to determine what's missing to get a match going in WD. Most of the time it's just waiting on healers but you just never know exactly with how it is now. :/
