Ok. For arguments sake lets leave the English out of it and just use common sense. Terminators cannot jink!
Jink is a term used to describe dodging with a vehicle. Terminators are infrantry
Tactical Dreadnaught armour is very heavy armour preventing the users freedom of movement. ie it can't jink
Common Sense and RAW are not on speaking terms. And if we were playing by fluff, then we'd be playing Codex; Movie Marines. Neither is it a rule to describe dodging with a vehicle - it's a rule for Bikes, Jetbikes and Flying Monstrous Creatures in addition to not-Heavy Skimmers, and Flyers. In fact, more non-vehicles make use of the rule.
And sure, lets leave out the language of the game we're playing. I know, lets play it with Wingdings! What sense does it make that a single character who is stealthy mean that it can stealth an entire squad? What sense is there in;
Acute Senses
Adamantium Will
ATSKNF
just to name 3, that apply to the rest of the unit?
Compare the wording for Jink and Deep Strike; "in order for a unit to be able to deep strike, all models in the unit must have the Deep Strike special rule and the unit must start in reserve."
The intention is for the unit to be able to make a jink, but only for certain people (i.e those models with the Jink rule) to gain the Cover Save. The wording potentially doesn't support that. We all know what it's "meant to say", but that's not "what" it actually says. Hence the comment "about an intentional misreading".
