Lujo Since that picture was taken, the following changes were made:
All heroes got a base damage buff.
More damage bonuses became available.
Sun Rings got buffed. Multiple times.
You can't use 2 of the same trinket without an exploit, but that's a moot point as Moon Ring + Quick Draw is the gold standard anyways.
Critical hits do +50% damage instead of +100%.
AoE math is multiplicative instead of additive.
Accounting for all of the following, damage spam as shown in that screenshot would deal 40 critical and 13-27 normal. Which still makes crits instant kills on anything you'd spam AoE on, and AoE spam a 2 hit kill otherwise.
Now as stated before the screenshot does not illustrate typical results, as you do not typically have 6 Moonshine barrel buffs + other buffs in effects. Standard steady state damage spam is 10-19 AoE, or 23-44 single target. It also uses Hellion instead of Highwayman as Highwayman has always been just like a Hellion but worse for no reason. PS: It's -5% crit, though you use white hits for your damage spam and the crits are just there for free stress heal (which you actually get more of, because it checks each of the three targets individually).
Stun spam is no comparison. It drags out the fight, makes RNG fuck you, and makes you grind more for no reason. Damage spam kills screens before they move, which prevents all damage anyways. Stun spam has only ever been relevant as part of exploit heals, which still work with minor workarounds despite their 4-5 "more than a fixes", and their one countermeasure that even kind of works (the stun buff) is bugged and triggers several times off one stun, and is also worthlessly small (which is why I realized it did nothing after a few days, then rapidly raised it until it was 5x the original value... of course, I also made stuns useful by making enemy actions worth preventing...).
Town Events have been vaguely described. They're basically Giant Alien Spider curios that you can't opt out on and appear randomly, creating more grind. Naturally they will never elaborate even when asked...
