I was thinking about the nerf last night and again this morning, and once again Bungie is messing with PVE for PVP reasons.
A few observations from a sub-par player:
Everything in the game is already a bullet sponge because of the Max level +1 balancing they have done, so decreasing the effectiveness of IB by 37.5% only means that players will go through content slower. (Black hammer nerf increases this downtime)
Places to camp and use IB: CE Bridge, VoG Oracles, Valus T'Arc tank, ??? (I don't know where you all camp, but these are the only ones I camp at with IB, and is it really camping?)
Cluster Bomb (Gjallarhorn/ Hunger of Crota): This means it takes longer to go through adds, there forcing us to camp and go slower
It appears that the intent here is to force us to go through content slower.
I foresee a lot of Sparrow skipping sections of Strikes in the future, until Bungie nerfs them as well
---------------
That all being said, I do think that the Thorn Nerf is actually pretty impressive. It only affects PVP
Also, I think the Hard light buff is a good thing.
EDIT: How many folks will switch to Patience and Time now instead of IB? I know I will, third eye, and Active Camo? Going to spend a lot of money on synths though
