Ok, I see where you’re coming from, but there’s still a few issues I have with this.
Imagine a long rush by the Ts with a CT AWPer holding the angle. Being able to fire accurately even when full blind gives the AWPer a chance to fend off against a rush by the Ts. If inaccuracy was in play, the CTs would have nearly zero chance of maintaining any control of long at any time. Flashes don’t need to be entirely precise to full blind someone, flashes over long doors full blind CTs effectively. Again, this would encourage more aggressive flashing.
The point of flashes isn’t to completely incapacitate their ability to fight back, but to make them less effective in gunfights. They should still have a chance, otherwise it becomes like CoD’s stun grenades, which the majority of people believe are bullshit. Sure, getting a kill while flashed may be “lucky,” but there’s nothing unfair about it. Same thing with getting kills through smokes. A well-timed flash doesn’t guarantee a kill by the person who threw it, and a well-placed smoke doesn’t guarantee you won’t be killed through it.
