I don't understand where Tyrell's STR boost theme is going. This, To the Rose Banner and House Florent Knight seem to fit that theme, but there hasn't been any additional STR pump for them since the Core, which were all restricted to the challange phase, limiting the interactions with the new cards.

I will have to test it, but this card seems to work better as a banner than in faction. Tywin, Gregor, Robbert, new Catelyn, TRV+Dawn/Doran, etc. are probably the best way to trigger the stealth.

Agreed. 

I think they're a little paranoid about giving too much Strength buffing to Tyrell but at this point it would be nice to have a new option or two. 

How would the Roseroad Patrol's conditional stealth work with Lord of the Crossing? Say for example, my opponent highest strength character were 4 and Roseroad Patrol was my highest strength character (or I have another character who gets boosted above the other side's highest character), is it correct that the +2 from crossing would kick in at initiation of the challenge thus giving them stealth?

If participation in the 3rd challenge you initiate with Lord of the Crossing gives one of your characters the highest STR in play, the Patrol would gain Stealth.

However, since that +2 isn't gained until initiation of the challenge is complete, and choosing Stealth targets is part of initiating the challenge, if the Patrol is one of the characters attacking in your 3rd challenge, it will not actually gain Stealth until it is too late to use it in the challenge.

So the answer to your question, "How would the Roseroad Patrol's conditional stealth work with Lord of the Crossing?" is "Not well."

what about using it in combination with the Wardens of the Reach, they can gain some pretty high St pretty quickly with the number of The Reach locations?

How is highest/lowest STR character defined? Is that a character that has to have more STR then any other character in play or if there are multiple characters with the same STR in play do they all satisfy the highest STR qualification?

Example, if i control two characters with 6 STR and no opponent has more STR that 5 do i get stealth?

Highest STR means no one else has higher STR. Doesn't necessarily require that you have higher STR than everyone else.

Is there any official ruling on highest/lowest STR from developers cos I didn't find it in core rulebooks. Florent knight was also a problem for me.

I don't know about official rulings, but that's certainly not needed. All characters who share the highest strength have the highest strength (and obviously same for lowest). If you have one of them, Roseroad Patrol has stealth. You may choose any character with the lowest strength to remove with House Florent Knight.

The card is worded, "While you control A character with the highest STR in play...". This wording allows multiple characters to be tied for the greatest STR value among characters in play, and so long as you control one of them, you are set.

The tendency seems to be to want to treat the card as if it said, "While you control THE character with the highest STR in play...". This wording would require that there be just one character with the greatest STR among characters in play, and you need to control it.

So there really doesn't need to be an official ruling to tell us how to interpret the card. Its text is sufficient to mark the difference between the various interpretations people want to apply.

But if you specifically define "character with the highest STR in play" as a unique character, in other words a character that has higher STR than any other character in play including your own, than it doesn't matter whether there is an "a" or "The" before it, and i think that was the case in the first edition iirc. If you do not, then you are right.

But why would you define it that way? There's no 'if' involved, the language is not ambiguous.

1st Ed. did not define it that way.

"The highest STR in play" is a unique value - i.e., no other STR value is higher than it - but "character with the highest STR" does not, by itself, indicate a single character. "Character with the highest STR in play" was (and is) simply a character with a STR value which no character exceeds. Whether or not other characters can have the same "highest" STR value (that is not exceeded by any character) depends on the article you put in front of that phrase.
