"You don't find an issue with the fact strikes can be completed in 1/5 the time" The way that sentence was worded sounded like you meant that the activities got completed in 1/5 the time (that it takes to complete the activity without the weapon) which means a whopping 80% reduction in playtime. If it said something like "You don't find an issue with the fact that strikes can be completed 20% faster" than I wouldn't have written all that. As for the point itself, no I don't find any issue with the fact that completion rates are 20% faster. In the end, we're still playing through their content. If they want players to play for longer or not complete activities as fast than design activities that are inherently challenging instead of taking the easy way out and simply nerfing guns so players have a harder time completing activities. A more inherently challenging activity leads to a more rewarding experience. It would also help if the rewards were conducive to wanting to complete activities (aka PoE terrible rewards). Instead of nerfing guns so that the new batch of weapons seem more appealing why not use that time to create better and more creative guns that would entice players to use them over current ones? I saw no issue with BH at all. It was a fun gun to use, it was unique and had a great niche as a stationary bullet sponge annihilator. Now it's likely going to be vaulted over perfect roll snipers which I'm sure was one of the devious intentions behind this nerf.

1/5 = 20% :)
