My main concern with warpcraft is not the content itself but timing. Every additional influence die we get now will help us in the future by giving us the freedom to choose additional options, making up for any die not spent on military in turn 1.
A second concern is the focus on Norscan raiders. I'd expect that the Storm of Chaos will be won or lost in a land battle in the Empire which would require us to send an expeditionary corps if we want to be actively involved. The main issue I see preventing us from sending that corps would be a major Dark Elves invasion which the fleet should seek to prevent.
In addition, I'd imagine that higher legitimacy of our rule and better internal stability (which is one of the goals of "Establishing Ourselves") will make it easier for us to send that strong corps when the Storm hits.
Finally, while the image of the warrior king is an appealing one Ulthuan has many powerful mages, capable generals and powerful champions but only one king.
In regards to the words, for the last one, we are a magic weilding king, not a warrior or general. Us being both a sorcerer and warrior and being a Phoenix King, means in-directly were trying to make a High Elf version of Malekith, outside of everything buy his combat prowess of course. Which if done right, is not at all bad, and it helps set up for the fact that alot of the things were going to do are martial inclined, since it's warhammer after all.
For the other two, the norscan threat was bad enough as it were, that for an admiral of the imperial navy to get in 2 year's enough ships captured, to not only retire several years and decades early, but pay his men's pension for over 20 years and by three mansions in entirely separate provisions. The problems that norsca can and will do, cannot be understated whatsoever, nevermind that they are just the first of several chaos worshipping groups/armies that are going to form a possible threat that can land on ulthan if they get resolved enough to try and do it. They have Wulfrick, and that guy can definitely do it. And being better linked with the courts has no bearing whatsoever on troop morale and skill when we are talking about something on the same scale as a storm of chaos.
The talk of trying to gain better favour with the courts and understanding, while nice is a bit of a massive oversimplification of how Ulthan works. Nobody is willing to try and fight against the Phoenix King and spill blood over a disagreement involving said Phoenix King. At most right now, we are basically the new king that most noble hope will do well, maybe be even great, but so long as he tickles their fancy when he does, then the kingdoms are satisfied and won't raise a fuss. Nevermind it's only a year, their not so selfish as to be offended with the a person not seeing them in a decade with a species whose life expectancy can range well into the thousands of years. Honestly, I'm thinking the thread aught to just try and think of the nobles as nobles, the rich, aristocratic, scheming, patient, and flexible people that can be very loyal when your thinking their not. Rather then caricatures that they tend to be heavily portrayed as in fantasy and historical medieval work.
