Guild Wars 2

As one of the many who dislike RnG in this game, I would like to suggest recipes to combine tonics in the mystic forge in order to create the endless ones. By doing this, people who have terrible luck would also have a chance at these exotic tonics. Naturally, the number of tonics needed to fill each slot in the forge should be 250 or more (if it’s even possible).
Comments/opinions are welcomed.

I exchanged 1 gold for 366 gems and bought the 10 fine transmutation stone pack.
The gem store slowed down for a bit (maybe lag) and the transaction ended. It deducted my gems but hasn’t sent me the stones.
