I do not like this idea.
Starting a guild back in the day was hard enough.
Starting a guild now, or trying to grow one without a highish level composer? A nightmare.
Composing takes years to ascend. (or should)
In the old days all it took was a concept, or a funny name to get folk to join your guild.
I know. I did it.
Now folk look for stuff and things.
You can be sure one of the things they look for is composers.
I get asked about it already.
Make it visible? A guild with no composer above level 37 can forget it.
The unintended consequence of this idea (one of them) will be to stunt new guild growth and to concentrate recruitment into the already top heavy guilds.
This is not a good idea.
