E right now, safer than Q which can get frustrating in QuickMatch. Q is more upfront burst though.
My voice is too high and nasally.
When you want to snowball or you aren’t afraid of the enemy locking down and murdering you. Be that due to reckless abandon or confidence. Deadly Charge lets you kill people reliably by yourself.
No idea on number 1, and you pick Extended Lightning whenever you feel you don’t need the extra healing and want something more reliable than CDR.
Yes, it’s when you want more burst damage and want to ensure that you snowball. It’s more damage than the Q talents after level 8 when you only hit a 2 man and hitting a 3 man it gets better at level like, 20.
