Yes it makes a big difference, but it works both ways. Gargs have an inherent "bonus" when using imbuing. BUT...that makes them harder to train up. On the other hand humans are not blessed with such an ability, so they are easier to train to GM, but they're not as good as a gargoyle at getting crafting bonuses. I was in the same boat as you. I solved the problem by making a human, which is easier to work with, then once he GM'd I bought a race change token from Origin store, and...PRESTO! A GM Garg with all the extra bonuses attached:]
I have NEVER heard a bigger bunch of whoooeee!
The only thing being a gargoyal does for you is give you a better chance of succeeding a imbue by 3%... AND THATS IT.
It does absolutely nothing else.
So when your imbueing a 5th slot on a item you have a 17% chance while I have a 14% chance. OMFG I have to hit the imbueing button one more time than you.
If you would rather save 1000 gold versus being able to ride mounts, wear armor and use weapons (from doom for example), and not be limited in a bunch of other things.... you go right ahead.
And he waited till GM too switch huh.... Someone should have told this guy that there is absolutely NO DIFFERENCE in gains on Siege when you hit 70.0.
Norman... you need a cup of coffee and to WAKE UP.
