I've encountered SO many problems with it because of people spamming.... usually just spamming linked items.
This isn't just a zone, or area, issue either. Its a problem from guildmates.
Guilds are creating "silence" ranks, just to make life more bearable and stop the bleed when losing players from their rosters from being annoyed at others.
Sure, I can block players. That's great. And I do... but I now have a block list a mile long... and I have to block them from my PSN completely (which means, even in other games they are blocked and they might only be spamming badly in this one).
Here is what I propose...
1). The ability to mute channels (like zone for instance... especially when in the Undaunted Enclave zones - where the linking of items has become so bad that the item is gone from the 10 lines before you can even read it).
2). The ability to mute ALL linked items from chat. This would be a great "catch all" solution to people spamming their items in chat.
3). The ability to LEAVE a certain channel (just like you do in voice channels) - and come back to it later if you so wish.
4). Multiple channels for Guilds (like the voice chat ones) that can be joined/muted/left at the users discretion.
