That is the problem. Who claims it too much with respect to who?
140 clear was a push with fishing. Wizards and Necro just cleared 147s. Even with their 3GR nerf they are at 144 GR right now.
What is too much? With respect to who too much? Are the questions we have.
They should just leave 200% as is or if possible buff it a nudge more to 300-400%.
This would give
1.17^x=4------>x=(log 4)/(log 1.17)=8.8 GR level instead of 7 GR levels (so 141-142 clearability)
1.17^x=5------>x=(log 5)/(log 1.17)=10 GR level instead of 7 (so 142-143 GR range)
Actually according to performance analyses, barb needs about 10 GRs so 400% lamentation buff is totally acceptable.
