ok gonna toss my two cents in XD

DRG is one of the best burst melee damage dealers i have seen so far, SMN has magic. from what i have done you can crit upwards to over 4k, heavy thrust disembowel work main combo pop blood for blood and life surge full thrust will crit for about 1.2k to 1.4k, power surge internal release jump hits for about 800 to 900 crits for same amount as full thrust, lead up into dragonfire dive that hits for about 600 to 750 crits for 1k or more, reapply heavy thrust and should still have time on your blood for blood and internal release as well as disembowel for another run of the main combo and adding even more, especially if it crits. numbers may vary depending on gear and weapon :3

ok thats my two cents XD probably not as educated as most but eh i tried ^^
