Personally I'm not against FP, especially when I'm shooting at something. For me it feels more natural to shoot guns in FP.
However, I enjoyed the TP in the WH series a lot as well. The combat, Geralt himself, the environment, the dialogs, etc. just look/play so much better in TH (not like we have FP in vanilla WH series but here I'm comparing it to my other gaming experiences).
I understand that in Cyberpunk 2077 there will be much more shooting involved than it is in the WH series and it makes sense to have FP. BUT this is an RPG game tho...
CDPR loves to make bold moves and I really appreciate that. There's gotta be a reason why they want to make it FP. I think CDPR should either convince us with some gameplay footage or maybe have both the options be available to us (I don't care how long it will take I will wait for it and I will preorder it the day it comes out
).
Hope this helps
