Phrasee's AI is testing a huge number of variables simultaneously to build a deep understanding about what resonates with your audience(s). So if every Phrasee line created for a split test isn't too generic, then we'd urge you to test them. 

Some may feel generic, but there is a risk here of adding personal bias into a machine-led experiment if you change them. The performance of certain variants you felt unsure about may well surprise you.
