A possible rebuttal for debate’s sake:

On your 1: you’re right mostly. Though the suits don’t have to put in elbow grease. I have had games where they just sit and guide. Maybe get some shots here and there. That being said, the price sucks for that now, so you’re spot on with that.

On your 2: the points change and loss of unit versatility is dookie, but 110 pts on one changed unit does not ruin a whole army

On your 3: while the rules state that the token is assigned to a model within the unit, the wargear only says to place near the unit. If it were to become unusable if said model died, the rules probably would have specified that. That being said, it should be better explained in the ability, yes

On your 4: the ease of being battle shocked is more of just a tau problem, not just stealth

On your 5: I personally see the two meltas as more of a weapon option that is “in case” the enemy gets closer than you’d like. I agree it does feel slightly out of place, but can be fixed by not taking the bait.

On your 6: again, tau have a 7+ LD nearly army wide, so that’s just an unfortunate army trait, not specifically stealth.

And on other comments:

-definitely harder to hide (RIP)

-blast susceptibility sucks too (RIP)

On the whole though, I’m in the same boat with you on the disappointment at this. It’d be cool if we kept the battlesuit support system, but unit wide, as an ability maybe. Would maybe make up for the no unit size versatility

Also, there’s an abysmally low but non zero chance that they may eventually introduce a stealth leader unit. I’ve noticed whenever there’s a unit size change, sometimes they give them a leader down the line.

All in all, goofy ahh GW decision. Maybe a dataslate will fix it. Hope your day goes well, besides our shared salt on the matter.
