If you're an experienced Fiddlesticks player, I'm pretty sure you're gonna know how big the AoE is anyway. It's not like Frozen Domain in that it remains static, it's centered around you, and on top of that enemies also actively try to get out of range as well, so that indicator would be pretty pointless like half a second after you ult.
