So automated turrets and robots are next in line, along with changes to ponies in power armor...given that I just watched a Unity alicorn tear the power armor suit off a steel ranger and beat him to death with it.
As for terminals...the Stable-Tec Terminal is a placeholder and is intended for only basic skills and spells. More Ministry Terminals will follow (For example, a Ministry of Peace Terminal will be required to learn from surgery hologems, as well as develop advanced drugs like Rad-X, while the Ministry of Wartime Technology Terminal will account for military training skills).
I've encountered the same problems with energy weapons as described during development, so they are low-priority for now, except maybe for interactions limited to robots.
As for cutie marks...I considered herbalism to be an easy skill, among others, so I improved its learning rates...and combined with the natural earth pony bonus this may lead to some high learning rates with certain talents. This cutie mark system is a holdover from my first mod, but I eventually intend to upgrade it along with everything else.
All of my animals (Yes, even cats) have natural skill levels (corresponding to instinct) to increase their deadliness in combat. It's why even feral dogs can take down ponies when in masse, and is especially !!FUN!! for more dangerous creatures.
Again, thanks for the feedback everyone.
Edit: Steel rangers and Unity alicorns have trapavoid, as otherwise cage traps would become the preferred means of defense rather than clever Stable construction.
