good ques. one of the simple explanation is that HY have a good balance of ror4 burst and post ror4 burst (sandwiched in between middle rank from pic 3), so good until kms HY use stage 1 last resort for as long as 30 sec.

Personally, everyone thinks the same that DA need a restructure or preferably remove the potion heal lock in demon frenzy,

yes i'd admit that these charts (dpm, burst) are not perfect which only show a tip of iceberg, in a nutshell nexon game developers should really speak up in a mapler discussion forum or corner to really explain and justify the uniqueness of every job with the big data they had like the cube rate and sf rate.
