What are Buccaneers like after BBP?

I'm still deciding between making a hero and a bucc, I know pretty much enough about heroes so far but I know around nothing about Buccaneers.
I have a few questions about Buccs that I'd like to be answered

1)Do buccaneers still have invincibility frames (after BBP)? are they any different than what they used to be before Big-Bang patch? what skills have invincibility frames?
2)Which major changes were made to the buccaneer job skills after BBP?
*Optional for a bucc to answer* 3)Would you reccomend me to make a buccaneer just for the fun of it?
4)Do Buccs have better/equal to/worse DPM than heroes? if better/worse then by how much?
Please state regular training and bossing.

Thanks in advance

1 a few, not like pre though. Screwpunch lost all of it's frames aside from the initial rush (like how warriors have I-frames right now). only Backspin has noticable after animation i-frames. Barrage retains it's iframes as well as demo.

2 there were lots: including 6 mob screw punch and spammable dragon strike. Bossing is better due to semi faster demo, long s trans and major watk boosts.

3 Buccs are good for fun, but i can't tell cause it's been a while since i've played a marauder/lower pirate. Plus BB may have changed their playstyle as well.

4. DPM cannot be determined due to the fact that BB patch makes DPM/S more dependant on how good your equips are instead of crit class= beast.
