Ok so the fusion page is not up to date but based on the current fusable armors listed the best chance of getting an epic would be from fusing a 4* Earth and a 4* Water with a 27.3% chance of yielding an epic. Fusing a 4* Fire and 4* Air is guaranteed to yield a 4* or an epic but only a 14.3% chance that it will be an epic. Fusing a 4* Earth with a 4* Air is probably your best bet at not being totally disappointed, with no chance of yielding a 3* and a 23.5% chance you end up with an epic.

Again these numbers are based on the current Fusion Armors page on this website and the numbers can significantly change with the addition of more 4* armors and epics.
