The kits on Mythic haven't been updated or changed in a very long time. I think they were last edited, must have been over 6 months ago. The current screenshots on the store are from more than 4 months ago, as Rogue put them on there, and she left the staff team then. I asked around the staff team about those items being removed from the kits, but no one seems to remember them ever being in there (I'm not saying they weren't ever in there, but just trying to work out when they were). We normally make posts about updating our kits on our Discord. We always listen to feedback when changing store items, and as this is real-world money in play, I always want to make sure everyone is happy with the changes. If we didn't in this case, then I'm deeply sorry.
We don't change kits or items often, and it rarely the case we remove items, unless they cause issues or now banned.
The teleport cooldown was removed from the ranks when we redid them (They didn't work on most servers anyway). We made a big post about the changes on Discord, and I made an update video talking about them.
There is a disclaimer on our site about the kits updating, it was under the important info button at the top of the site: https://store.kineticnetwork.net/important-info
The button was removed to add the new ToS for our new gateway, but it was there when you picked up the Blood Magic kit. It's our mistake that it isn't there at the moment, and I'll make sure its added to another part of the site ASAP. I'll also add a message to above where you buy your kits, to make it more clear.
Thank you for your feedback, I welcome input.
