you have to remember that until the info is submitted, it will stay that way.
However i can give you a bit of info on cracked earth. its AoE..does about 100 damage (around level 30 anyway) and does NOT root immediately. i use it when i solo but not much...you have to cast it then run and hope all the mobs get rooted eventually.
lm's get an actual aoe root at later levels, close to 40 i think.
