Typical case of a player calling themselves a "veteran" to make their misinformation more believeable. First of all, efficiency is never ALWAYS important, especially since "veterans" will have more access to more means of energy recovery: Rage/Hunter Adrenaline, Zenurik, etc. Efficiency is great on frames with powerful channeled abilities: Equinox and Excalibur come to mind straight away. However, some frames have single cast abilities with long durations: e.x. Chroma with Vex Armor and Elemental Ward, and Mirage with Hall of Mirrors and Eclipse. In that case, you're best off building for duration; you'll most likely recover most of that energy by the time the ability ends, and not putting Streamline or Fleeting Expertise (which will actually HURT these frames with its Duration penalty!) on them frees up mod slots for power strength, duration, or range. And Flow isn't a mod to be discounted, having many use cases: for example, while you definitely should build duration for channeled abilities, most of them disable many forms of energy recovery. Since you can't use energizing dash, or benefit from something like EV (especially if you're playing solo, where you can't have other frames make energy for you), a bigger energy pool = more uptime for those abilities, without having to disable and recast it. And Flow benefits many niche playstyles too: Quick Thinking + (Primed) Flow means a huge secondary health bar, allowing you to beef up your frame's tankiness substantially. Like Channeling? Streamline won't help with that, but Flow will keep you going through the occasional energy droughts.

TL;DR: Flow is not useless, efficiency is not the end-all-be-all of Warframe builds, and having more hours in a game does not mean other players deserve to be insulted for not following your advice.
