Fast answer
Tideon is worth building when you want a stronger mid-path Water line and your account is already serious about Water pressure.
Best use
Tideon feels most useful when:
- Water is already a real part of your roster
- your account wants stronger evolved Water output
- you value longer-fight consistency over one short burst window
Verdict
Tideon is a more committed Water investment than a stopgap line. If Water matters to your account, it is a clean route to respect.
