do you not see?
Lotp is 45y range, which is needed for the 2-3 hunters which will try to be as far away as possible (some of them because of talents increasing their damage when they are further away)
Rampage isn't even comparable with only 20yards.
Right now, we have Rampage as 275 AP (10% more ap in berserker does not add 10% more from critrating..). And we would have gotten raidwide 5crit from Druid.
To make matters worse, BOM is not planned to stack with Battleshout but to be equally effective.
So now we loose 242-2xx AP from BOM and 275 from rampage.
Congratz, fury has lost 500 AP in a normal raid setting while gaining nothing they didn't have before.
