Since the disease duration is up towards even 2minutes and with solo/smallman there is often no way to cure yourself, it would be very nice if there was a way to deal with this somehow.
So my suggestion is to add two types of new alchemy consumables.
In the case for disease, it should not be a balance problem, since it is spammable.
For nearsight however, putting maybe an even longer cooldown on it might be reasonable - to not make NS too weak.
Example of use conditions:
Alchemy Cure Disease: Out of combat for > 10 sec, 1-2 min cooldown
Alchemy Cure Nearsight: Out of combat for > 10 sec, 3 min cooldown
