There's no unicorns, rainbows or sugar coating it....facial hair removal is a long, expensive, painful and tedious task. Also, it seems my entire life revolves around my hair cycle. Without laser, 200hours doesn't sound unreasonable. I'm a fan of laser, it made a big difference to my skin appearance quickly and even if some of it works out to not be permanent (YMMV) it was worth it to me.
As for your technicians strategy. My face tends to swell pretty badly when staying within the same area so I'm fine with a scatter technique. Unfortunately, the scatter technique is less rewarding because it takes longer to see larger sections of smooth skin but I would rather not be bruised, excessively swollen and/or scarred.
