When you've gone a while and your T1 relic forging looks something like this:
Bronze setting of will: 121
Bronze setting of might: 133
Bronze setting of morale: 108
.....
...
...
...
...

I must have over 1000 to combine in T1 alone, let alone T2/3/4/5/6...

It would be AWESOME as an option to include an autocombine-all so that you can nail an entire tier at once. Like with crafting, you're giving up your option to crit on each and every combine, but at least that way you don't have to auto-combine for 25 min. across your levels.

Just my 2 cents.
