Don't underestimate Sunsingers. Huge skill ceiling to play well but hot damn.
Bad ones are free kills, good ones are unstoppable. My second-most feared class. Voidwalkers are just an annoying cheap kill every once in a while, Sunsingers can run the table if played well.
True enough. Just like a bladedancer can be taken down in a 2v1 scenario...
...a bubbled Defender can as well. However, attempting the 1v1 is folly.
Unrelated note... I will say, there is nothing like coming across another hunter in Arc Blade. The resulting battles (especially if you're both using Blink) are so tense, frantic and fun, I'd play an entire game mode of it. It's only happened to me 3 times ever, but it's a blast.
holy crap i'm actually referenced in a post... in a good way?

edit: HAHAHAHAHahahaha, someone asked if it 'was real?'
How many matches did it take me to warm up last night???
