This is what i got back from MA support.
Hi Little Star, Thank you for clarifying that you mean the Block % buff on the CUHOF Armor Plate V. We reviewed the information available to Support, but could not establish that the missing buff is a fault. We also cannot confirm from that review whether it was intended or promise a change. We are unable to interpret item mechanics or confirm how different upgradeable plates should compare. For gameplay discussion, please refer to the in-game item information and community channels. Kind regards, Entropia Universe Support
From this i have to conclude the "missing" buff is not a fault.
I’ve raised this several times with DME, in game, on Discord, and on the forum, but still haven’t received a reply.
I’ve always understood that the PP is responsible for listening to the community and balancing its planet-specific items. Since that hasn’t happened, I thought it was reasonable to bring this to DME, as they announced the new items.
I believe armor plates are part of a progression path that many mid-level players work toward as they upgrade their gear. It’s a shame to see another missed opportunity to attract new players and give this small community a reason to stay on the planet (we all love) and pursue the new item.
Upgradable armor plates that give block chance:
Armor Plating Mk. 5B (Caly)
Armor Plating Mk. 6A (Caly)
Serpent’s Scale (NI)
Incision Plate (NI)
Imperium plates (Cyrene)
A.R.C. Laceration Plate (Cyrene)
Lunar Plate (Ark)
Moonshine Armour Plate 1/Smugler Plate 1 (Ark)
Aegis of the Gorgonforged (NI)
Upgradable armor plates that
DO NOT give block chance:
CUHOF Armor Plate
This makes Cuhof armor plates into the single only upgradable armor plate ingame that gives no block chance buff.
