I have a quick question.

Atm I have a level 49 full Dex birdie will some half decent gears in my stash. However I was told that the Sunblessed Blow was probably the best way to go for any of the bow choices. But i've been using my level 47 purple Ballista thus far and my damage is insanely high at the price of 1.2 DPS though. I have a pink Ballista of fortune for when I hit level 50 and I compared the damage to both bows and if all I really care about is efficiency and high damage output, does it really make that much of a difference to blow my money of the Sunblessed Bow?
