hexside combat modifiers suggestion/discussion

[wololoh]

Hello,

I wonder, if it would be possible to make some hexside combat modifiers different for melee and fire attacks. For example, for streams it makes sense to me that there should be some melee modifier. however, that means the stream will also stop bullets because the same modifier is used also for fire attacks .
Thus currently the PDT setting basically gives a choice:
    - either streams have no defensive benefit at all (no combat modifier)
    - or they will also stop bullets (because they also apply to all fire attacks)

In my opinion it would be nice if we could set a negative modifier for melee attacks across stream, without affecting fire attacks (or different/less effect on fire attacks).
And maybe a similar distinction could be made for other terrains as well. What do you think?
(Note I do not know the engine limitations of course, maybe it would be much too hard...)
