| You already said the pros and cons, so at one way u already had decided wich one u want ^^
U sould know what u like to. do u want cool looks and nice dmg output use fire.
u want to freez and combo usw water. Its depending on ur game style ^^
for example im wind/water because im going light witch to support.
i use water because it got the best one target spells and fressz options. so i could save my life while is support my party.
an friend of my is wind/earth pure aoe going soul master, he only wants to make much dmg in a fast way and hit multiple monsters. so he used this way to go.
and ur not really different. if u look on youtube for example there most lightning ^^ |
