Growth is not needed of course, as the tunes work very well even without it (perhaps death is too much though).

Yes you are losing some research, but as dryads are also pretty good commanders (40) they can lead small armies. With tunes they can cut down on troop amount directing money to fortresses leading to faster research.

I can agree on that dryads are not the best unit to use initially, though later on you will have loads of them as you hire them as researchers as well. Some of them could be used behind enemy lines accompanied with revelers and cause some damage. You might have noticed that they now have +25 stealth making them ideal stealth preachers whom are also capable of defending themselves.

Harpies are good for scouting and patrolling, that is for sure. Thanks for the tip.
