Opening -

20:1 - The charge spinners are independent rather than shared.
3:1 - Voltage charge at 5x rather than 4x.
2:1 - More charges required to drop shields

I'd be ok with all of those, however the very start of the Raids tend to not change at all on Heroic. I'm pretty sure that part isn't even a Darkness Zone either.

Vosik -

10:1 - Lockout on picking up charges
2:1 - One room lit each time
2:1 - Multiple monitors light at once

Sure, that would be pretty fair.

1.5:1 - Monitors on the back and sides can activate too

Woah, slow down, Satan...

Siege Engine -

10:1 - Additional part to install
2:1 - Less time, more enemies

That dude that hijacks the zamboni is, IMO, underutilized so far. Maybe he has a bigger role now and shoots down or something. I also expect a LOT more mines on the way.

Aksis 1 -

10:1 - 5 shots instead of 10 in the scorch cannon
5:1 - 7+ targets each time
2:1 - faster servitor movement

Eh, can't imagine anything other than those.

Aksis 2 -

10:1 - Only two platforms
10:1 - 5 shots instead of 10 in the scorch cannon
3:1 - Aksis drains your light and the supercharge is the only way to get a super

I also expect supercharging being central to the strategy this time. I originally couldn't picture them forcing you to use a particular class to keep DPS up, but since the Viking Funeral buff, I guess every class has a DPS booster (Weapons of Light/Melting Point, Tether, Viking Funeral), so it's be totally reasonable.

- No text -

Great thoughts. My though was that the servitors in the final two phases will attack you instead of just floating around.

1:1 There are way more yellow-health-bar enemies. Because yaaaaaaaaaay bullet sponges...

Opening -

Nothing different.

Vosik -

Single lit room + back and side monitors light up

Siege Engine -

More enemies

Aksis 1 -

Increase in targets and you have to hit all targets per round. no change to number of servitors per round

Aksis 2 -

- 410 light enemies (This is a given at this point right?)
- Supercharge is the only way to get supers
- More servitors/bombs needed to drop the shield

Not likely
- Captains replaced with Rahndels
- Bombs/Targets from Phase 1 also included.
- Continual servitor spawns

Vosik's first stand:

• Nothing, apparently. Maybe the charges drain faster if you fail to kill those Shanks.

Vosik NASA control room:

• 6 bombs per throw, instead of 3. Need all 6 to do the same amount of damage, it seems.
  
• Doors are half-closed with airlocks, forcing you to slide in. (As if we weren't all already doing it :p)

Death Zamboni:

• Kill Mr. Meeseeks (look at me!), get a Splicer Tank to spawn.

Tame Aksis:

• SIVA turrets to brighten our day. Who could've seen that coming?

Mad Aksis:

• Two Servitors per door per spawn.
