What's your secondary? parry is always a safe bet, Whirling sword is always handy. LBE is kinda pants IMO!
Defiant 50's
Many and varied!
@Miss Chief
Regen, heard somewhere the defence gained from parry with regen doesnt make all that difference, might go for whirling possibly 
Parry makes a huge difference to a Regen. Whirling Sword is nice too but I wouldn't take it since you don't have Slice, might as well go all single target.
I used to think Parry wasint all to good to ill 'speced it out, and boy it comes in handy.
My opinion on the BS attacks is;
Hack- Must Have
Slash- Not too good little Damage
Slice- Alright, very good IMO optional though.
Parry- Very good but again optional to your play style.
Whirling Sword- Good for AoE damage, not too shabby either.
Disembowel- Get it, slot it, love it.
Head Splitter- No Words to describe it 
It's that good.
Did I miss any?
Edit>>> Yes.
Build Up- Get it, very usefull with Headsplitter and Disembowel.
Taunt- Ok but it's optional to your play style again.
Parry, clearly.
You haven't got Parry yet??? Well, especially with regen Parry rocks! Just 6slot ist with 3 Acc and 3 Def Boost and you'll gain incredible survivability against smaller groups of enemies.
Except from that, I must be so impolite to double post some parts:
Number 1: Kudos on picking a BS/Reg Scrapper. It's one of the late blooming and most versatile Scrapper builds there is. Well, it's only lethal damage, but who cares? You do so much of it, that it don't matter.
My Build for Strife (BS/Reg) made it all the way to 50:

Tips:
Take Parry. Your path to EVIL survivability. Imagine an enemy type rarely being hit, regging fast, dishing high lethal damage and is quite unmezz/hold/stunnable. Anyone except a Tank would clearly hate its guts.
Take Resilience. It's a taste thing but will dramatically increasy the utility of rezz inspis and reduce downtime due to being disoriented. Heck, without Resilience, my Assault Rifle/Energy Blaster could Beanbag you to oblivion.
Consider skipping MoG. I lived fine without it.
Go for Focussed Acc. You already did this, but it definitely ROCKS! Paragon Protectors: MoG my (censored), you'll hit straight through that with added Buildup.
Slot Headsplitter no different than: 3 Dam, 1 Acc, 2 Rech. Thus, with Hasten running you can fit two Headsplitter into the 10 seks of Buildup: Builup, Headsplitter, Disembowel, Hack, Headsplitter. The second Headsplitter will commence at 9,x secs of Buildup giving you beautiful damage Output.
From 41 on, everything is up to you. I took Intimidate for PvP. Take whatever you enjoy. Port for FBZ? Concealment? Fear? Whatever. This build is perfect from 42/43 on. Everything else is just icing.
is whirling sword a good choice , not many ppl seems to take it and those who does dont slot it ???
It's good all right!
But we are talking about a power combination with huge potential.
If you can have:
- unique single target burst damage
- high survivability (with Archmage+Instant Healing: Godlike Survivability for 1min)
- beautiful PvP capability
- and one good small range point blank AoE
What would you slot?
In general, solo you rather need single target damage to quickly reduce enemies damage potential.
In groups you *could* use it with Buildup at the beginning of the fight. But alas, the AoE mayhem already comes from blasters. So I'd recommend doing what BS does best: Go straight for the big guys on the enemy side and takte them down!
If you want an AoE Scrapper, Spines/Regen might be nice.
PS Do get Archmage. It'll drive people crazy in PvP combined with Integration, Resilience and IH! You basically can take the Alpha while your team puts their tactics into action.
sry but, [censored] is archmage ?????
Archmage: Accolade Badge (easy to google) give you the "Eye of the Magus" Power:
Incredibly boosts your Res and Def for 1 minute every 25 minutes. Combined with Instant Healing you're basically almost a Stonetank with an Empath Backup.
however its pretty hard to get that accolade cause of the banisher and illusionist badge needed
"god, how many devs did hami have to sleep with to get ED?"
Total Cat @Stagefright
yeah i can see its hard with all the things i need to do , looks pretty tough
Yeah, it sucks to get the accolade.
But no character profits more from it than a */Regen Scrapper with Instant Healing.
All right, it's only up for a minute every 25mins.
But that means you get it and you can stay 4% of Gametime in God Mode.
Excellent for PvP, too. Group of 4-5 Villains hanging round?
Just use IH, Archmage, burst in and hit and run a squishy. You'll take down 1-2 squishies as they feel that superior that they just don't run.
Did that once and was directly accused of cheating.
Lo all, am currently about 3 pips from dinging 48, and am thinking of what power to take next. I already have hack, slash, build up, disembowel and head splitter. I got the choice of the rest of BS, or laser beam eyes.
Any ideas guys and girls?
