Shotgun Mods, Accelerated Blast Vs Flechete

[Y4gers]

Well, today I noticed something quite interesting while working my loadout for the sweeper. Flechete is a drain 9 mod, giving 30% Puncturedmg. Accelerated blast is drain 9 as well, but gives 60% puncturedmg and 60% Firerate. Now I dont want to call it a real bug, but I believe that wasnt intended that way, or? I might have misunderstood the basic concept of the nightmare mods, but shouldnt they combine 2 effects whilst in both effects being weaker than the original mod? Cause right now, nobody who owns both mods, would pick flechete over accelerated blast if he has to choose only one of them. (The only reason I could think of, would be not wanting that 60% additional firerate for any reason, but I cant think of a situation where that wouldnt be a benefit) 

Pls correct me if Im wrong there, but I think DE might want to have a look at those 2 mods again...

I agree wholeheartedly. Flechette used to be 90% puncture, vs. Accelerated Blast's 60% Puncture + Fire Rate. Damage 2.0 changed that for some reason.

AB needs to be nerfed down to 20% at max level (5% per level) to keep it in line with Flechette.
