So far as I recall (since bundling), that's always been the case.
Indeed, it was either requested or complimented upon (probably both) when the system was put in place, because people could use different arrow descriptions for different capabilities. These ones are for hunting fire-critters; these ones are for cold-critters; these ones are Blessed for undead; et cetera.
Now, if you're one of those people who is in it just for the +20 on the arrow and you don't really care what the flare is so you're unattuned and getting random ones each time, then yeah I could see where that would be annoying.
