But if this is the case, then why would he use them in the first place.

It says that the AoF weave is composed of two flows, Fire and Earth.



However Blossoms of fire are composed of three flows. Earth, Air and Fire.



Now consider it.

If each arrow of fire was a single weave, then to shoot just 100 filaments, would have required 100 weaves, or 200 flows.

However with the same amount of flows, Rand could instead have created 66 blossoms of fire. Which do you think produces more damage to an incoming trolloc army, 100 filaments which each could kill 1-2 trollocs. Or 66 blossoms which each one producing huge explosions that take out trollocs at "hundred paces".

The only thing that makes sense to me is that the AoF thing is a single weave. If not, LTT is a complete idiot for wasting such huge amounts of flows to produce single filaments when with only a tiny more effort he could have produced blossoms and taken out tens if not hundreds of times the trollocs.

Add to this the fact that in the scene, the weave is referred to as a singular.


But the description is multiple



And it seems obvious enough to me that a single complex weave can be used to shoot lots of filaments. One weave composed of fire and earth to produce lots of filamentS.
