I can deal with the ground-star patterns for red and gold card being gone (mostly, Red one is completely different), but what I cannot deal with is the new sound effects.
I mean, this was a visual upgrade... not a sound upgrade. Gold card sounds like Kat's new E, Blue card throw sounds like Zyra's plant shooting a dart. Red card is average at best and stacked deck + wild cards metal-slicing sound is just off.
I recognize that the new gold card animation wouldn't fit with the old sound... but if we can't have it back, can we at least have something different? It really sounds like Kat's E... and that pisses me off.
I'm sure many more people will notice the similarities... Personally I loved the old gold card sound, both the throw and the glorious impact. It is one of the things that defined TF imho.
Those are the only things that annoy me... other than the small wild cards animation and the kinda tall model (both of which im sure will get fixed soon), it's a good change.
Tl;dr: Please bring back the old sounds for PaC (or at least the gold card one). either that or get better ones... the current ones seem rather recycled.
