Just a heads up if you plan to do elites. using gale in elite can annoy some people xD and yes clock is hands down better than gale. reason being is that i would rather have a root for 8 seconds rather than a stun for potentially 4ish seconds and clock lasts the entire time of its cooldown so basically you can continuously root mobs, how awesome is that?
my general build is a hybrid (pve/pvp):

fire - 4/5 (without scorch)
lightning - 3/5 (no stun and no AoE)
clock - 4/5 (no bomb)
curse - 5/5
shield - 4/5 (no knockback)

reason i dont use heal is it arguably the worst heal in the game xD my mana pool can last for a very very long time. and the heal is next to useless for me in elites as well im better of spamming pots

passives are 5/5 for might, knowledge and agility
all stat point goes into int

if youre going for pve only get rid of curse and allocate your point elsewhere

good luck
