A couple of issues with the new, improved Animals:
1. I have had two Hunters and an Assassin killed by Animals - two Wolves (strength 7) and a Gorilla (strength 9). Those are powerful animals, but in each instance my guy had nearly 99% defending odds, so I think something might be amiss here. All were Combat V, with Subdue Animal, and 2 had extra first strikes.
2. I saw an Elephant that was strength 14. Holy Powerful Pachyderm! With over 500 turns left in my epic speed game, I wonder what is the limit on strength for animals? Could they end up stronger than the Avatar of Wrath?
3. I wanted to capture an Elephant, but my Hunters, even with Subdue Animal, were hopeless against them. I am just now getting Rangers, but at strength 14 I am not so confident. Anyway, I want to see what happened when you captured a strength 14 Elephant and turned it into a War Elephant. Has anyone done this yet?
4. I managed to build the Grand Menagerie early - a good thing, too, as these animals, if they are allowed to hang around get very strong and also pick up a host of promotions as apparently the AI sends low-level units against them.
5. As animal units, why don't my Stooges gain strength over time like Bears, Lions, etc.?
6. Maybe this was a change I missed in FF, but why do captured Animals NOT have HN status? Now it appears only the Stooges and that Nightwatch you get from Deception are HN. I guess if you build units in cities with CoE, you have a chance of getting them too, but I used to like to have HN Giant Spiders and Griffons for some early game fun.
