Ok the my suggestion is up front followed by my reasoning.
Just allow us to use the existing Emot Wheel to store custom 'Text' messages of say up to 500 chars each.
It would also be nice if we could have set of say 3 or 4 'Wheel' mappings so we could store custom message for some specific common complex dungeons.
Yes, there is already an Emot Wheel, and it does have some very basic useful messages like:
Attack Boss
Attack Adds
Ignore Adds
Follow Me
Point
Ready Check....
That is ok for some situation but if you have every tried to do an even simi-complex dungeon where no one else in 'on voice chat' you would quickly find these are inadequate to describe even moderately complex mechanics like.
Must kill boss before 3rd Major attack or it causes a team wipe.
Use levers to stop gas AoE
Must fight boss on stairs
Or even simple general information like
There is a Chest here.
Trying to use the Xbox controller to write even a small message dynamically in a dungeon is a huge pain in the arse.
Even using a chat pad takes too much time in the heat of the moment since you still have to go through several screens and open the 'Texting' window at which point your character is just getting wailed on.
It would be great if everyone just used headsets and spoke but the reality is almost no one does, especially in 'Random' dungeons with strangers.
I bet PC users have an in game 'Text' hotkey solution...
Even if the game does not support it directly I am 100% certain there are free hotkey mapping solutions.
Hell they existed for 'Everquest' 20 years ago.
This is not 'Just' as important for Console users it is 'More' important since we don't have any 'Keyboard Hotkey' addon app solution to fall back on.
