So ....which towers are your favorites, which do you use on a daily or weekly basis? For me it is:

Usually during Heroic races I may use Ramsey. During breeding events I might click on Damona and/or Broodby. After a race Hanzo may see some usage. In desperation during difficult temp tourney's Winstance will be pulled out of hibernation but Phaun is just useless....period. Ironic that the hardest to complete is the most useless, stupid one they have come up with.

Oh no, Phaun is very useful in providing me some extra food when the dragons fail to find the next piece :)

Seriously though, I think all towers are ridiculously useless feature in the game with the reload times that they have and minuscule benefits they offer. I'd say to make them useful, SP needs to convert them to some permanent effect. E.g., Midarian could be just "increase gold production 20%" without any cooldown. Jewelem could do a couple of gems a day + store them (e.g. up to 5 or 10 gems). Broodby/Ramsey/Damona/Hanzo/Phaun could be converted from a "effect+cooldown" into just some permanent perk, e.g. "Your food grows 20% faster" or "Your dragons breed 20% faster".

If a cooldown is desired, then it may be some second, powerful feature that requires maybe even longer cooldown. Sort of what "Exertion" ability in MtG does. For example, for Midarian it may be some lump sum gold bonus, or for Damona it can be "Finish all breedings currently in progress".

Jewelem hands down, I only use that one and the twin duo regularly.

I use Jewelems and Speedy Greedys every day. Ramseys is useful in races. Damonas and Broodbys are good for breeding events. And Winstance helped me to win a timelimited tournament. I tried Phauns for a breeding event but it didn`t give me something special.

@Nynaevelan How much is Ramsey's cooldown ??
The first time i used it was 84 hours I remembered

S&G is my favorite, Jewelem and Midarian get used daily. Ramsey when it's available (more food is always a good thing). Hanzo when a new dragon needs training; Broodby and Damona during breeding events. Winstance when getting a new dragon experience. I agree with the comments about Phaun being useless. It may actually be counter productive if it causes a long breeding that isn't the dragon you are trying for.

I use Jewelum & Speedy & Greedy every day.

Midarian almost every day - sometimes I forget that one.

Don't use Winstance as much as I used to. Usually when fighting with a new dragon.

I use the ones for speeding hatching & breeding occasionally, but it's frustrating that I have to wait so long between uses.

Phaun was more useful before I completed it. At least I could get a little food or gold from it. I don't bother using it at all now.

Hanzo gets used if I remember it when training a dragon.
