Broil: 340p
Biolysis (30s): 70p on cast, 30p per tick, 370p total
Miasmalysis (24s): 280p on cast, 10p per tick, 360p total (this is a replacement/upgrade for Ruin 2)
Shadowflare (15s): 100p on cast, 50p per tick, 350p total (this is an AOE puddle)
With these potencies, simply spamming Broil for 24 out of the 24 GCDs per minute would be 99% of the effectiveness of the current Dawntrail SCH's GCD output (and that includes DT SCH having to use Biolysis). The difference between '24/24 Broils' and 'using the DOTs perfectly and not missing a single tick of any of them' would be about 2%. The DOTs would be effectively 'ignoreable' for players who aren't seeking to do parse runs, and because of that 'ignoreable'-ness, they can be used instead as mobility actions to keep your damage rolling while running around, since they're instantcast.
The above example would take a SCH from using 22 Broils per minute, to 15.5 Broils per minute (the decimal is due to getting 5 Miasmalysis per 2min) if they want to interact with all of the DOTs. But for a player who does not want to DOT, they can simply ignore the DOTs entirely and still clear literally every DPS check currently in the game. In fact, they'd potentially find it easier to clear those checks, because if they use Miasmalysis only at the times they'd currently use Ruin2, the on-hit potency of Miasmalysis listed here is higher than Ruin2 (which is currently at 220p).
