If I'm parsing rexscarlet right, the point seems to be simply that people are having trouble adjusting to the new
LoS rules. Not necessarily that they're bad, or good, or wrong, or right, just that in the
OP's experience, the transition is fraught with questions and confusions.
I'm not sure what can be done aboot this. People need to read the new rules and get used to them. I don't think there's anything at all confusing aboot the new
LoS rules, the only places I can see issues coming up is when people already have expectations for how it works, and then don't actually read the new rules.
in order to help make the terrain and the different types of terrain distinguishable and functional?
Yes, definitely. I would hope that the terrain
GW supplies will already have this in mind, but there's no question that the new rules demand a new look at terrain.
It would seem that some people (insaniak has said he's one) have been playing a very 5e version of
LoS for a long time, so there's no surprise for them, and their terrain is probably fine.
However, for others, who treated
LoS a little more loosely, it may be necessary to cut windows a little bigger, at a little more useful/consistent height, in order to avoid unduly hampering shooty armies.
A green base of woods 12” X 12” would have a darker green center 6” X 6” to distinguish the 6” from the edge; in order make clear the 6” to shoot out/in rule.
Very clever and very useful in 4e, but obviously no use in 5e. Instead, 5e seems to demand that woods be far more "densly planted", possibly with removable trees, if they're to provide the 50% obscurement a vehicle would need to get cover behind them. It's my feeling that a vehicle totally behind a forest, which used to be totally oot of
LoS, should get at least a 4+ save now. Unfortunately, this requires that the terrain be built to do this, and it leads to rather annoying terrain as a result.
