I'm fully aware that the whole attribute system of KMOD is not very deep, it was put together in a very short time for the 1.0 release and little enhanced in later versions (in 1.x, speed influenced only movement, in 2.x it also influences melee weapon delay which gives a lot more sense to up it for the Fighter). Upping strength for the Mage is only there for show, I know... this has to do with the fact that KMOD is built on the same codebase SE is based upon, and in SE the Mage will have a melee weapon too, like the other classes.
While this aspect of KMOD will most probably never changed (barely any development is planned for it ever), any suggestions regarding its RPG (or other) shortcomings are very welcome in the Scattered Evil forum
, since that is still in development and thus new ideas and enhancements can be built in.
Also, damage of both melee and other weapons will be modifiable through physical upgrades or magical enchantments in SE - I think strength as an attribute should really only modify melee weapons.
Regarding speed with the Mage, I'll leave the field to one of our coders, as I'm not sure whether the speed spell (and the Boots of Speed, which is the same effect) influences weapon delay too, or only movement speed.
