I'm not fond of quite a few tank animations in general (except for gunbreaker and maybe warrior whose kit feel solid to me).
DRK's Hard Slash feels like he can barely support the weight of his blade and pushes it forward in an awkward unbalanced pose so gently that it feels like he wouldn't deal much (if any) damage before he falls over.
Soul eater feels like the DRK jumps out of nowhere and with not much power behind it it looks to me like he just jumps while holding a slab of metal perpendicular to the floor kinda like a dolphin jumping for a trick.
It most of all feels too disjointed to be called a combo to me, like there is no continuity to the 3 gcds aside from the fact that they glow. These feelings carry over to PLD :
Aside from the lack of impact of holy spirit's cast and even it's vfx.
Fast Blade: it feels like you're pulling a lame scare on someone screaming "HA HAAAA ! got you there huh !?".
Prominence's jump feels unnecessary : We start with an attack on the ground and the next gcd we're levitating/floating whilst vigorously swatting flies before being gently put back down as if we were held up by cables in a theatrical piece.
Basically Fast Blade's brevity makes it feel disjointed with the following Riot Blade to me and Prominence's jump feels goofy. (Royal authority's slow 360 jump kinda makes it feels like a free real estate opportunity for a dragoon's spear to lodge itself into us but since it's the end of the combo I guess it serves to add due gravitas.)
i'd also like to use the shield more and see the animations of *burst phases* spam like holy spirit following requiescat or delirium be more varied like gunbreaker's continuation combo's animation diversity. Paladin's Blades of virtue combo following confiteor feels like a decent exemple of that too when I think about how the blood spiller and holy spirit spams don't feel as impactful as the fell cleave one.
