Mmm I use a Guardian and a Warrior-I am not too enthused about this on either end for the following:
-For full DPS type of Warriors, they would have to sacrifice a bit to get to 30 Discipline (there are 30 Discipline DPS builds of course, but not all are, and if you use defensive traits with 30 Discipline, you’ll have even less offensive output-just more critical damage.) It is very much like those Grandmastery traits that turn defensive traits into offensive on many Professions-they improve damage, but you are already sacrificing a bit of it just by getting the trait, so there’s almost always a trade-off.
-The Warriors, while a strong Profession in many ways, still has some problems that this “boon-hate” won’t address, since it’s just a specialized build to deal with a few specialized enemies. To be honest, I wouldn’t even use the trait vs any other I could use instead, or a 25/25 build somewhere along the traits. At worst, it seems to force Warriors into a 30 Discipline build on PvP scenarios. IMHO, “boon hate” may make Warriors being more used, but just with 30 Discipline, which isn’t good for diversity (I have nothing against 30 discipline, but wonder what’s the use of this if every Warrior will use a similar build anyway, moving forwards? Must be hard being ANet. :P)
-Guardian is still powerful enough to deal even with a Might signet, “boon-hate” warrior-they can stun break their way out and dodge, push Warriors away (that lack stability, of course), use Shelter (I wonder how new Signet of Might will interact with it-damage for the first 3 hits followed by blocks?) and even with Save Yourselves, Protection will protect them quite nicely.
Note that I am not saying it is an “useless trait” as I am sure many will take this opportunity to devise strong PvP offensive builds around it, but I am sure Ms. Willa will ignore it and fight as usual as if nothing was patched, until more interesting traits are offered her. I don’t think people should be that fearful of it unless a massive Warrior vs boon-oriented Professions domination occurs.
No offense to the developers or anyone else, but I never thought much of this Warrior “boon hate” even while it was talked about and being tested. Hopefully they can prove me wrong and it’s strong, balanced trait that isn’t too overpowering.
