Why this works for RF

Harvest is the only major mechanic with essentially no damage check. Plants come to you in a fixed arena, they die to an aura, and nothing is on a clock that costs you rewards. Its main cost is attention, not gear. It is also how an RF character fixes one specific problem. A missing resistance, a wrong socket colour, an item one mod from finished. Budget players usually have exactly one thing wrong, and Harvest fixes exactly one thing.

What will brick it

• Management cost. This is the highest-management strategy we would recommend, and the current write-up implicitly admits it by spending four paragraphs on plot ordering. Rate it High up front and let readers self-select.
• The lifeforce-selling advice is trade-only and must be marked as such. An SSF reader following "check which colour is worth more on trade" will be confused. The live copy has this problem today.
• Tier 4 plants are meaningfully tougher; a budget character should expect them to be slow.
• This is the strategy people burn out on, and burnout is a real cost for a casual audience.

Swap off this when

The plot-ordering starts feeling like a job. That is not a joke. Concretely: when your gear no longer has a single fixable problem and you are only farming lifeforce to sell.
