I'm somewhat in disagreement with the proposed Spy changes.
The Amby change will serve to only make it more frustrating for the Spy who misses despite aiming well, and frustrating for the guy who got headshot across the map because he knows the Spy's crosshair was not on him. Was the Amby a bit too strong at long ranges? Debatable. I think ever so slightly yes, but it was a high skill dependent mechanic. I think a more fair nerf would have been increasing headshot cooldown even more for less ability to follow up, or something along those lines.
As for Dead Ringer, they've just sort of killed it. Spies running it will now just hide in a corner waiting for it to recharge, not contributing. It isn't very conducive towards engaging gameplay. The current DR is without a doubt unbelievably stupid, and in general the DR has been hated for a long time. But the thing is, I think the DR really got asinine the moment they gave it a speed boost. The old DR where you could tank a shit ton of damage was stupid as well, but atleast Pyro's genuinely did wreck you, and you didn't have access to all ammo kits on the map in an instant. Perhaps a balance needs to be struck, or maybe we could just revert, I'm not sure.
Either way, I think the combination of these two nerfs absolutely hurt Spy in game-modes where he is permanently run (Highlander and Pubs). I understand a need to make Spy feel more sneaky, but realistically, what sick fuck is going to want to go 8-30 in a Product official where the enemy Heavy is doing nothing but Spychecking the entire game? Gunspy needs to still be an option for Spy players to keep their sanity in both pubs and highlander. I recommend more messing around with the DR.
In 6s these changes won't affect anything so this was all useless fluff. Huh.
