Aren't you talking about "sales" which may appear 1 month (if not quicker) before game closing?
But seriously, 50%off should be a regular price AT ALL, Armas IS overpriced as it needs a change. If there will be 75-85%off oh dear, sadly I have most of Armas items I'd like to have so I'll pass anyway, I may consider if it'd affect also PS4 version IF it gets actually "fixed".
Kttc is bad imo because you only get a regular Vegas. Also it comes with guns that are useful, but not things I would ever buy off armas because 2 out of 3 are f2p guns. The whisper is something I might consider, but you can get one from retail packs though with worse mods.
Kttw at least gives you a 4x4, but again I would never buy any of those weapons. The atac is good, but premodded stuff is bs. The stac is another f2p weapon and I guess the tin soldier is alright.
The best pack is probably the juggernaut pack tbh.
There are no retail packs for console versions.
Vegas 4x4 is currently META, yes, but I'm addicted more to Jericho/Pioneer/Rapier.
Jugg pack hv really ugly clothes, the same as Rev pack, only these boots from Jugg are cool and myb that hat is also cool.
Weapons are really good, I think on consoles they might be performing even better than on PC.
Still Imo if you hv no anything from Armas (I.e you would like to play on Ps4 instead of PC) then KTTC is the best option (obviously during Sales)
You have there awesome 2 clothing packs account wide and useful weapons, I don't mind that these weapons are F2P and only Oca Whisper is sth "new", I'm totally fine with that:)
Also some ppl would buy JMB's so, maybe overpriced, but still you would be able to buy legendaries from other players.
Forgot about Vaquero, it's not bad car either especially with Enfo kits.
