Skill gem forge

I have been playing mostly Templar so far in HC and what I have noticed is that when I get skill gem drops, they mostly are blue or green and very rarely they are suitable to me (red).

My suggestion would be that what if they would be a some kind of skill gem forge where you can eg. put 3 skill gems and it will randomly generate a new skill gem from those 3. Just a bit like a horadric cube in diablo 2.

Also an option to craft basic gems somehow would be nice.

The reason for this suggestion is that when I watch for passive skill builds for templar to survive HC, I often notice that most of the builds requires gems that cannot be aqcuired by any other way than pure random luck or heavy trading.

What are your thoughts?

Trading, and social interaction is an aspect of an MMO

However, as I said in the other post for something similar, anything that uses gems that you have for anything better, either random or on choice, will be exploitable because you can make level 1 characters, rush through to hillock, and give 2 gems to the stash for whatever character meets the requirement of the forge to use it.
