I found that my Kat/Regen wasn't too bad in Sirens even with a total PvE build. Accuracy wasn't that hot with only 1 acc slotted in attacks but I still did alright. As long as you're mobile, it's pretty easy to PvP with.
As for builds, there are dozens of Kat/Regen threads if you browse a few pages back on the forum. From Katana, the cookie cutter build is to take everything except Gambler's Cut and the taunt. It gets decent AoE and a melee cone, a couple of really strong single target attacks and one of the best defensive buffs in the game, Divine Avalanche.
There are lots of Kat/Regen builds being poular as it is but I wasn sure how many we recent enough post I7. I was well aware of the amount of threads there are on this combo. I guess waht I was asking was which is the most up to date that I can browse or have you a link? 
Alos was there any further info since well I7 is in and people have tested builds by now?
Thanks Idris.
I don't think I7 changed much for Katana/Regen TBH. MoG got a little bit worse, Divine Avalanche got even better. I haven't played my scrapper much since I7 but I see no reason to change my build at all, really
Agree with Idris: Nothing much has really changed build-wise for a kat/regen in i7.
With the defense scaling changes "Divine Avalanche" has become a good bit more powerful, and the katana attacks "-defense" secondary ability is more noticeable (though it's still not worth slotting for!).
Any of the i6 build convos listed should do ya. 
My current (i7) kat/regen PVE build is unchanged from the i6 one, which is listed in THIS THREAD.
Well my main is an MA/Regen and of course I knew about the MoG changes. Didnt know about any kat changes. Also I didnt know what previous changes did. Like in MA Crippling Axe Kick was greatly changed and Thunder Kick was made less powerful.
That was what I was getting at. As I say thanks very much for this and Ill point this thread and try and dig up the builds and such.
As Lodestar was so kind to post on my behalf, i want to thank him, and i would also like to thank you Idris for the replies.
I never quite understood why a scrapper would need the taunt attack when tanks are basically designed for that purpose and therefore i haven't got that attack, or gambler's cut (Gambler's Cut sounds as though it would need a lot of ACC slotted 
). In any case, thanks again, and i'll be looking a few pages back as you suggested.

Just speaking to a friend about her scrapper and I got to wondering what people are going for on a PvE build with I think a little PvP in for variety in I7.
Anyone able to help as I really dont know much on Katanna?
