Idea for a new Gamepress Calculator

What about a sliding scale of comparing raid bosses based on Time Left in clock.

It would work like this:
Pick a boss:

Pick a level of Counters: Use Game Pressrankings: "Supreme/Good/Tank"

Enter Average Number of Seconds people in your area / normal raids beat that raid by.

Pick a 2nd boss

Calculator converts what an expected amount of time to beat the new boss with a similiar strength line up would be.

Behind the scenes the Calculator would have to
1) Adjust for Defense of varios bosses
2) Pick a new counter based on various counter list.

This would be just another tool for letting people get a feel for other raids and what to expect.
