My point is that over half the player base effectively get a full scale respec anyway (you can switch from any pure melee class to almost anything else, and from xbow to almost anything else). So the strength 2h that have dominated the game for years get to adopt the latest flavor of the month build for free, while classes that are already weaker (melee+ranged hybrids) have no choice other than a slightly worse version of what they were before.
How are you getting hurt? Please explain. And it's also debatable if a hybrid is "weaker" than a non.
(and, while it's not really efficient, my character is actually specced 1h/HX, but I rarely use the xbow. With this change, I'll still be the same, but I'll actually be probably 130/90 which is better than my 140/70.)
For your edit:
Using this opportunity to allow melee+ranged hybrids to dump their secondary role cuts down on the overall amount of ranged (which I think everyone wants), while allowing people to escape builds that are potentially screwed up by this patch.
If you can't play with a 18/18 build, your playing retardo war. 18/18 is the baseline from which you can compare all other builds. My change makes everyone, more or less restart there. So no, no build will be screwed up, and if it "is," it's because of the player trying to min/max themselves to much.
