1. So, what if I have an uneven number of old blue Mercenary scrolls? It will only allow me to combine one of each to get the higher tier one. Sorry for my language, but this is bullshit. In my case, it means that I can't convert about 100 blue skill scrolls to the higher exp + skill version.

2. How about you add a way to exchange these old blue Mercenary scrolls via NPC, because

a) this Simple Alchemy stuff is awful time wise and

b) this way you can also add a way to exchange one type of scroll to the other.

3. About the name: before we had Mercenary's Skill and Mercenary's Experience, the combined Scroll is also called Mercenary's Experience. Just as a suggestion, why don't you name it Mercenary's Skilled Experience that would fit way better with the change, I think.
