Let's pretend for a moment that this wasn't already specifically regarding questions of whose throughput fell short, such as why a group is failing a dps check, or that such a question is somehow not most directly answered through metrics related to throughput.
You seem to be falling under the misconception that parsers can only measure DPS. ACT may call that satisfactory (though it includes more than that as well, just not via its mini display), as it was made only for those who particularly needed DPS metrics (for raids that are ultimately cleared or failed because of DPS), but that's far from from the limit of parsers.
Percent active time, enemy active time against you (a.k.a., kiting percentile), (de)buff uptime, specific (de)buff's uptime, specific (de)buff's uptime against a focus target, avoidable damage taken, number of instances of avoidable damage taken, vulnerability stacks acquired, deaths, raid time spent rezzing you, healer % uptime spent healing your avoidable damage taken, total mitigation, average percent mitigation, average %HP decrease per strike taken, average %HP decrease per strike taken above a set threshold, damage percentiles by source, incoming damage by source, effective healing done, overhealing done, average overhealing percentile, average overhealing cast as portion of total healing casts, damage dealt to specific targets, overkill percentage, and the like are all displayable in real-time through parsers.
