Based solely on this text, I would say yes, Harbour isn't as good of a contender for Viper right now compared to how she's been seen in comparison charts and general opinions about her abilities.

Here are some key points that might explain why:

1. Slows: While it does mention that having more effective slows is 'a really good idea,' the suggestion seems to be extending them further rather than just implementing better ones, which could suggest Harbour's current set of slowing abilities isn't quite as impactful or long-lasting as players would like for her role.

2. Mobility and Damage Control:

- Viper can move around largely unscathed while still applying pressure through damage on enemies who enter certain areas.

- The comparison suggests that this kind of control is something Harbour currently lacks, making it harder for her to effectively counter or harass enemy players in the same way as a well-played Viper.

3. Ultimate Comparison:

- High Tide and Toxin seem designed differently: one creates an area effect immediately while taking up resources (fuel), whereas Toxin takes longer to activate but has a wider range of effects.

- The fact that it's mentioned alongside these specific abilities from other characters suggests Harbour might not have the same kind of high-impact, game-changing potential in her kit as Viper does with hers.

Overall, based on this analysis and assuming there aren't any other relevant factors or context missing from your question, yes, Harbour doesn't seem particularly well-suited to fill the role of Viper right now.
