I totally agree that Team Attack is an essential tool for Heroes to be able to cope with larger threats like Titan and the like.
The original poster (OP) mentioned a post he'd seen earlier. Specifically, "I saw a post from 2016 that talked about team attack with three individuals stacking damage to determine massive damage... I believe the example listed as attack 1 inflicts 10, attacker 2 inflicts 8, and attacker 3 inflicts 12 or something along those lines."
I think the post he's talking about is likely the one I linked earlier (
viewtopic.php?f=24&t=2234) since the date and numbers match the ones he cited.
I think the question under discussion, though, is how exactly Team Attack is supposed to work mechanics-wise.
Massive Damage is normally only determined once per attack. With Team Attack, I think Massive Damage is actually supposed to be determined LESS than once per attack (like, once for two attacks, or three attacks, or however many attacks went into the "Team" pile of damage).
My concern about double-counting works like this. From the ongoing example:
1. Devastating Attack#1; 20 Stamina = TN20
Saying "TN20" implies that these 20 damage exceeded the target's Fortitude and are therefore used to make a Massive Damage roll with a Target Number (TN) of 20. If this roll happens, then these 20 damage have now been applied to one Massive Damage roll.
2. Team Attack#1; 10 Stamina = TN30 (20+10)
Saying "TN30 (20+10)" implies that the 10 damage from this Hero's attack is being added to the 20 from the previous attacker to exceed the target's Fortitude and trigger a Massive Damage roll with TN 30. If the previous roll happened, though, AND this roll also happens, then the 20 points of damage from the Devastating Attack made earlier have now been counted TWICE, because those same 20 points of damage have been applied against the target's Fortitude two separate times.
That's the part I'm uncomfortable with.
For myself, I think the mechanic presented in the thread I linked above is what was intended - two or more Heroes add their damage together and then make a single Massive Damage (i.e. Vigor) roll once they're done Team Attacking.
The main question I have is: What kinds of attacks can be Team Attacks? Everything? Basic Attacks only? Headshots? Devastating Attacks? What are the restrictions? Are there any?
