Coming from a super casual that likes things to be fun over all else, even I think all DRG and SAM AoEs should be cone/line and the other 3 mDPS should be circle AoE. For tanks, their AoE combos should 1st hit cone (longer range) and 2nd+ hit circle (shorter range).

If they want us to use 3rd Eye, change it to 15/30s cd, reduce dmg by 25/50%. I simply do not care about a negligible 10% dr.

The Kaiten outrage is surprising to me. Always felt like a nerfed Life Surge from DRG and I never felt it was part of their core identity. Identity for me was always "lots of combos", inherited from its FFXI roots of being able to skill chain with yourself. Still have this hanging around in a txt file:
~~ LVL 71 ~~
Tachi: Gekko
Tachi: Yukikaze
SC: Induration (50%)
Tachi: Gekko
SC: Fragmentation (100%)
Tachi: Kasha
SC: Light (300%)
Big hit is secondary identity, but is still there, at least for me: Midare does 66% more than 2nd highest potency regular attack I have plus crit - if that's not your definition of a big hit, I don't know what you want. In a burst window, you can still do 4(?) of these, and they all crit - we have 4 free cherries on top, instead of 1 that we had to place there ourselves. Animations and "fantasy" feeling are personal; so ignoring that, am I missing something about Kaiten (still a bit low level)?
