I think you will have to wait for more people to reach 50 for a varied and precise opinion.
you telling me that pll haven't gotten any 50s yet. Bah, it's been out more than a month. Lazy buggers. If you can't even trust powergamers anymore then who can you trust. 
A PL'd character might not write the best guide until after its been played a while as well you know
"Well, they found my diary today.
They were appropriately appalled
at the discovery of the eight victims
They're now putting it all together.
Women wrapped in silk
with one leg missing
Eight legs, one body, silk,
spider, brilliant!"
Irony is so waste on the masses... ;P
I think one problem is that what can be said about WP is so quickly summarised that it is hardly worth the effort to write a guide about it unless you really go in-depth with proposed attack sets and all that.
Thinking about it I just might give it a try this weekend. Expect something entertaining with hard facts centered on brutes that just may be helpful for tankers and scrappers as well. (Stalkers are in a different ball park I will stay clear of.) Don't know if the first version will be in German or in English, though. Stay tuned! 
If it has eyes, you can blind it, if it has blood, you can make it bleed, if it has a mouth, you can make it scream.
is there a will power guide out for tankers yet?
