Grid2 v2.8.93
Mists of Pandaria 5.5.0.61820

I'm using Beacon of Light on one of the range statuses to have my indicator show me when ppl are >40 and <60 yards away. But it doesn't work when people don't have beacon of light (obviously).
The player class&spec works, except if someone is below lvl36 and play holy, since beacon is learned at 36.
So would something like a spell known or player level load option be possible? Very niche use case sorry ^^

Try out grid2 2.8.94-mists

It is now working to choose primary/secondary in the load option.

I guess I thought it would base it on your chosen spec and not whether you were in your Primary or Secondary spec slot.
The load condition can't really be used consistently since you might have your "offspec" in the primary spec slot etc.

This can only work in this way in retail, in MoP blizzard did not activate the full retail API to manage all specs, they enabled a strange mix between vanilla and retail, so there are missing functions necessary to make this work like in retail.

I understand.

Weakauras have a "spell known" load condition which is perfect for these spec specific abilities, and could be used to also not load certain missing auras reminders and similiar statuses when they're not available.
