I've read the article, and the following direct references I can find for them talking about shields are this ones:
None of them seem to confirm your latter statement in which you state the only way ion systems is if a ship is unshielded. None of the direct references, and from what I read about the ion article go with what you stated.
In terms of you first statement,
nothing in my paragraph states that(the one you quoted) states that it bypasses shields. It states that it disables them, which canon confirms, as well as the other quotes I posted from Wookipidea. In terms of the stuff you quoted
here, it's common sense; deflector/ray/particle shields don't protect against ion bolts, something that is confirmed in canon, and something I already stated in the first page. It's a reason why ion canons are highly effective against conventional shielding.
The Tyrant is an Imperial Star Destroyer; I would like to show one thing:
The ISD's
deflector shield dome, per the Wookie page only protects against things ray and particle shields do, as exemplified by this quoet:
Not only does this go with what I states that ion bolts will affect shielding systems, it also goes to exemplify the fact that ion bolts won't be protected by both deflector/particle/ray shielding. That's why I am stating it was common sense that it will bypass the shielding, but I understanding for balancing purposes, you wanted that removed, so I was fine with that. Nevertheless, canon has shown it will bypass shielding.
