Global channel needed for in-game chat.
!! Needed for the trade channel to be global or an auction house. !!
The Barbarian has hardening mainly for Bash with DMG, other skills do not have such support (Forming for Enrichment).
PvP maps require enrichment with some activities and an interesting drop, maybe some additional helltide on PvP maps.
Expanding glyphs without limits - farming dungeons would make sense!! The character could still be slightly developed!
PS.
*The last big update (itemization + loot again) including non-season was great!!
*MMO Hack and slash is what the market needed!!
