I tested my Bots/FF Mastermind on the Beta, and this is a substantial nerf - I mean it.
Sorry for the long post, but I want to help as much as possible with information, so try to stay with me, here...
The damage increase is nice on the pets yes, but the -Regen is a massive, massive nerf against harder content, and here's why:
--1. Currently on Live, the Assault bot stacks 1,000% and sometimes 1,500% -Regen on a target. (I just tested this).
We're talking easily 100+dps on a level 54 AV. That's more dps than all your pets combined against a non-debuffed level 54 AV.
--2. To get full -Regen now, Masterminds have to take and slot three whole powers. This is a painful blow to power selection and bubbles.
Even if you pick up the three powers and spend slots in them, it's only -600% Regen. 1/3rd of what you got in Live.
So against 54 AVs your kill time is just destroyed.
This exacerbates a problem MMs already have, which I'll explain so try to stay with me again here...
Currently, a MM's biggest problem is effectiveness scaling via the Purple Patch. <-- that's a link!
Purple Patch TL;DL - the higher in level the bad guy is over you, the exponentially less you do to it. This includes debuffs/damage/to-hit/etc.
Masterminds have pets that are level 48, 49 and 50 - this is important to remember. You pets are not your level.
This means Masterminds are as good as everyone else at level 50 content. They're quite good, in fact. Support with average-low damage, like defender.
Now let's make the content level 54. All the other Arctypes are 48% as effective, except MMs because pets are 15%, 30% and 48% effective (in pet order).
This means the higher level the content, the further Masterminds fall from the rest of the team.
For example, I just did this on Live 15 minutes ago:
Target: Arachnos Fortunata
Mastermind's Pulse Rifle Blast against a 50 = 63 damage
Mastermind's Pulse Rifle Blast against 54 = 30 damage
-t1 Minion Laser Burst against a 50 = 3 ticks of 6.45 damage
-t1 Minion Laser Burst against a 54 = 3 ticks of 1.2 damage
The player does 47.6% of their original damage on +4.
The t1 minion pets do 18.6% of their original damage on +4.
Bump that content up to level 55 Challenge AVs and MM pets go to 8%, 15% and 30% effective.
This is also a To-Hit reduction on your pets of -92%, -80% and -70%. They really struggle to hit the higher level you fight.
4star Hardmodes:
Challenge AVs are 54+1, so t1 pets and t2 pets are basically doing nothing. The only saving grace was -Regen from the Assault Bot.
In this patch that -Regen has been cut to 1/3rd and the MM has to actually hit with 3 attacks to get that 1/3rd.
On Live I might allow a Bot Mastermind to come on 4star runs because of their -Regen against 54+1 AVs.
With this patch there's no way Masterminds would be useful outside of their Secondary Power selection, which is already weaker numbers compared to other arctypes.
In the end (thanks for coming), this is a buff to Masterminds doings Radio/Paper missions or fighting level 50s.
However, In Taskforces and especially in Hardmodes, this is a huge nerf if only because of the -Regen loss.
Here come my suggestions to fix the problems I see:
--1. Above all else, pets should be the same level as the Mastermind. Even if their damage has to be nerfed because of it.
If pet level is not matched to the owner, Masterminds will always scale worse than every other arctype.
To be as good as everyone against a level 50, but worse than everyone against a level 54+1/+2/+3 is poor design.
On 4star Hardmode content, MMs can't keep up - it hurts to watch.
--2. Give some -Regen to all the Robot beam attacks. Not as much as -1,500% (that's really OP), but enough to stack up to -500% at least without the MM using pew pew.
A Mastermind full-timing a support set like Kinetics or Electric Affinity rarely has the time for their gun, nor can they afford the power and slot picks.
And if a Mastermind isn't full-timing a support set, they can have the option to add another 600% -Regen to the target on top of their Bot debuffs.
Making all bots do minor -Regen with their lasers is consistent with damage-type design: energy beams do -Regen.
As always, thanks for the wonderful work you Devs are putting in. Current power updates are my favorite patch notes.
You work is so very appreciated!
