Felt like playing TF2 again for the first time in a few months and it took me a while to realize why my Dead Ringer was taking so long to recharge.
What the HELL did they do to the DR? Ok, I know what they did, but like, why? They've nerfed the DR a few times before in the past, but removing the ability to restore the cloak with metal completely kills the thing for me. I've always used it as a tool to let me play the aggressive spy, harassing the enemy team, then feigning, then getting a recharge and going back to harassment as quickly as possible and so on and so on. It was a fun way to mindgame smarter players and get them to make mistakes or waste their time on you, but without the ability to speed up your recharge this kind of playstyle is no longer possible. They've removed what made it unique IMO.
Half of all my time in TF2 is on Spy, so having one of the main playstyles I like to use essentially removed from the game is honestly pretty frustrating. It's not the only invis watch I use, I also used the C&D a lot, but that has a much slower, more methodical playstyle. It's not really a replacement.
There've been a few spy nerfs before that I thought were unnecessary, but in the end they weren't that big a deal. This is the first one where I think they went too far. Even if it's more balanced now it's no longer enjoyable to use.
