personally I think that LoL is pretty cool. Usually I field 2 wizards, 1 life and 1 beasts. LoL may not be the most offensive lore in the game but because of the way it works you can potentially attack units and such where ever they are on the table depending on the terrain.
I regularly play against a lizardman player and it is invaluable against him, I have marshed Cold One cavalry and over run them in HtH, nerfed his multiple shot skinks with howler wind (wizard in the centre of a large line of troops, over 100 infantry that he couldn't target), killed priests and sneaky scar veterans trying to creep around the edges of woods, in fact the only one I haven't ever needed is the healing spell.
I much prefer this lore over the more overtly violent ones such as Fire.
