No, you see... You're estimating, just like almost everyone else who actually count their drops to see when they CAN get an epic. It cannot be SAID that you'll get an epic next drop or after these many drops, you can only PREDICT you MAY get one.
well I predict with great accuracy in fact I just got my 5th hero drop and I get an item drop about every 6-7 hrs rrt so in 5.5 hrs I am going to pit and I will get an epic. I need a tc for rrt though so if you know anyone with one for 900k let me know man
Mounts would be a interesting "traveling" system buff. So you can move +10% faster so to say. With there being more mounts available at certain levels, and questline mounts. Mounts could also provide storage space.
