Werewolf transformation tips?

Pallmor

I've been a werewolf for a little while now, and I've leveled to level 10 and I've got most of the passives and abilities. But I still see other werewolves who seem to be able to stay transformed a lot longer than me. So I'm looking for tips and have some questions.

1) Is there is any sort of cooldown on devour? Should I devour every enemy?

2) How many seconds does devour actually add? I've heard 7 seconds and 12 seconds.

2) If devour adds 7 seconds, for example, and I devour the three guys I just killed, will I get 21 seconds extra time, or does it reset each time?

3) Does blood rage increase duration when you receive both magic and physical hits?

4) Are there any other tips to increase duration that a werewold newb like myself may not know?

-Feral Pounce adds 4 secs per leap with target at correct range

-Heavy attacks with pack leader morph adds 2 sec
