Yep, the drink nerf is pretty rough in combination with the toolset that Chin has lost.
The shoulder super is a lot better now though since you get the wall bounce even if the opponent is airborne, other options are weaker, and it is far easier to time the follow-ups than in KOF XIII.
For the record, Chin received two decent buffs in KOF XIV ver.2.00:
1. Chin's Gouran Ennhou (Fire Breath Climax) gained invincibility. It's 13F startup and nearly half screen range so it's great for moderate distance whiff punishing/countering in an emergency. Many other ranged supers either run out of invincibility before reaching half screen or don't have any invincibility.
2. EX Drink now fills the drink counter by 3 (+15% damage), allowing him to power up quickly and discourage the opponent from running away too much from Max Mode Chin. With Chin's drink counter at 3, he deals over 1000 damage off his standard qcb.AC combo starter if he lands two qcb,qcf.AC EXDMs in the combo.
To be more specific, I normally use qcb.AC, hcf.BD, qcb.A xx qcb,qcf.AC, run forward df.B~B, qcb.A xx qcb,qcf.AC, hyper hop CD to deal 1000+ damage with 3 drinks starting from 4 bars.
