your old rosemary is just that....old, tired and its roots will be very congested. It prob did get waterlogged and it seems you did the right thing...i.e. Drilling more drainage holes
have you fed it? pale leaves are a sure sign it is hungry
rosemary is not long lived ...although I have one which is several years old now....esp in a pot.
it is time to take cuttings...good time now...and prepare for replacing your plant Pot-head
so, feeding it now, and I would simply use a seaweed spray as well as an epsom salts spray and see how it does
