With Batguard Annihilation Field activated, followed by Charge, this should cause a Biotic explosion

Agreed. Honestly, they should change it so that charging from anywhere with annihilation on should trigger an explosion. Take off that on/off crap from field when charging. Because as of right now, unless they'd rather make right how hold the line works on all kits with shields active, there's no justification for this kit to be ultra rare. He goes down way too much for something with bastion and hold the line. I wonder if one of them aren't working properly.

It might just be that I've been playing the exemplar and avenger too much not really using soldiers, but man this guy doesn't feel right.

P.S. Not even sure, but has anyone ever tested hold the line mechanics when shields are back up but health is below 30% on other kits?  Does it not work on them too?  Or is this a special case/is hold the line broken on the vanguard?

Well, SP has funny Vanguard combos like DoT melee sword proccing Barrier Drain every tic.

I think it really shouldn't, as his punch provides for a biotic combo already. This character is perfectly playable as a Charge-Melee character for Gold and below, imho...

In fact - if this would be done, his detonating melee would be a bit of excessive. I.e. - either auto-detonation on Charge with Annihilation on and normal non-detonating melee, or as it is now, no auto-detonation and detonation with melee strike.

DoctorFox 's argument isn't about balance or already having the ability to detonate with his gauntlet.  While he maybe balanced already, logically, AF + Charge should always cause a detonation (assuming AF primes instantly) because AF should act upon a target before a Charge hits.  So it's unclear (at least to me) as to whether the combo is working as intended.  Based on what you said, and how little play testing it would take to confirm this behavior, it probably is working as intended (even if the interaction is unintuitive).  This also seems to give us some indication into the delay that AF has in priming, or that maybe Charge is animated as a line of effect power, but in reality is executed like a teleport power (like Avenger/Shadow Strike).

I think the reason it works the way it does is less about balance and more about the way charge works. I don't think the game attempts to calculate where you are until charge hits, so getting the annihilation field in the right place may require reworking the coding. Obviously there are higher priorities.

Ah, well, what gethadept said then. I don't think there's any delay in AF priming, btw...

Consider it as a price for gaining invincibility frame and teleporting ability.

BTW, if AF doesn`t get deactivated by charge and apply vortex to every enemy within its path, the game will have a lot of trouble.
It`s not just about charge + auto combo itself being too powerful. (It is too powerful with XX bonus)

Lore wise, BW won`t explain it.

But charge and Annihilation field  might simply be two biotic power impossible to co-exist.
Possibly because the difficulty of maintaining and performing both, and possibly because they both use biotic field.

I'll ask you the same question I asked Scathane , did you come up with that explanation before or after you knew about how the power interact in-game? My issue isn't trying to explain the actual interaction itself. In fact I went back at watched InfamousSparkman 's solo. And your explanation seems 100% correct. You can see AF shrink whenever the Batarian activates charge. My issue is that this behavior might not be listed in the power description, so this interaction is unintuitive.

I think you've been misinterpreting my tone altogether.  I'm not crying about it.  I'm just a stickler for consistency.  Like you said, you would expect it to work, but it doesn't, so we move on.  There's been a misunderstanding between the two of us.  I misunderstood your explanations for expectations.

I just wasted a decent portion of our time on something insignificant.  And for that I apologize.  I think that means I'm done posting on BSN for the day.
