The game should tell players that movement and spraying affects bloom.
Yes, there are a couple spread bugs (such as high spread when exiting sprint), but overall bloom is in quite a good state IMO. I have 15,000+ kills with ARs, 3+ KD, and am enjoying the depth of this mechanic.
90% of players are just completely unaware that moving increases bloom, and/or unaware of burst-firing or tap firing as a mechanic. They full-dump their mag while strafing at full speed in a medium or long-distance fight, and wonder why their shots don't hit.
These mechanics are great, and not new, but the game needs to have like a 10 second intro video explaining this to players. At longer distances, you don't want to be full-running and spraying.
Imagine if 90% of CSGO players didn't understand that moving affected accuracy. That's the situation we have right now because the game never explains these mechanics.
I really hope the bloom mechanics stay (especially the penalty for running and spraying), and don't get removed because of the complaints. Movement is meant to have tradeoffs and it adds depth and realism.
