After the Test Server update on 04.04.2025. Skill cooldowns were reduced, for example:

"Prime: Entangling Icy Thorns" The cooldown of the skill was reduced from 9 to 7. But you forgot about the skill "Prime: Stamma's Mate" Which also goes into combinations with 9 seconds of cooldown left. It also needs to be reduced to 7 seconds.

Nova has very few skills, almost the smallest number of skills useful for PvP and PvE. Therefore, it is necessary to reduce the cooldown of skills, or give 2-3 more skills with good damage.
Yes, you increased the damage. But it was 40-50% weaker in damage at High level. It became 20-30% worse after this change.
What I and many Nova players would like to see after this change:
"Prime: Stamma's Mate" Requires a cooldown reduction from 9 to 7 to avoid breaking the combo, and will also help with the lack of skills.
"Prime: Frozen Darkness" It requires an increase in damage by about 20% in PvE. So that it would be 9042% x2, to match the skill "Prime: Fianchetto" after the improvement the skill became 8875% x2.
"Prime: Storming Star" The skill was improved chain strike where there was no damage anyway, no damage increase was required. But the final blow was increased to 13664% x2. This is too little for a skill that is applied and hits after 2.5-3 seconds. Another increase in damage of the final blow is required by about 20% PvE. When other characters have slow skills, let's take the Guardian, they deal, let's take the skill "Dragon's Maw" and an additional hit "Flow: Howling Light", where in total it deals 53364 damage. When the Skill Nova, in 3 seconds of casting, it deals only 27328 damage.

"Prime: Icy Thorns" The final blow needs to be strengthened. It is now strengthened to 4596% x2, this is very little! It needs to be strengthened by about 30% more PvE. The first 2 blows are not given in PvE, only the final blow. Or rework the skill, removing the first 2 blows and leaving the final blow, making the damage there say 10000 x2, but at the same time strengthening Health Regeneration to 250 per hit.
"Prime: Swooping Ring" Requires Damage Boost by about 20%, the skill hits right next to the enemy, it is not mass. Requires Damage Area Increase. Health regeneration needs to be increased from 125 to 300.
"Prime: Star's Call" Cooldown reduction from 10 seconds to 6 seconds is required. This is the only skill that has PvP invulnerability and that lasts 0.75 seconds.

At the moment, even after the damage and cooldown improvements that have now been updated on the test server, Nova will still have problems with damage in PvE. Also with the cooldown of the same skills that went into the combination, you reduced one from 9 to 7, and forgot about the second, which will ruin the combination in PvE. It is necessary to reduce the "Prime: Stamma's Mate" skill to 7 seconds. She will also have less damage than other characters. Needs some improvement.
Nova is still not able to compete in Mass PvP. She has no function to deal damage or survive. She has only 1 invulnerability that lasts 0.75 seconds with a cooldown of 10 seconds! She has no function to survive after you have updated the "Corsair" which completely destroys Nova's block in 1-2 skills and she can't do anything after that. PvP damage increase is required for Nova if you don't add more life to her to survive in Mass PvP. Either adding damage in PvP, or increasing healing for skills, increasing invulnerability.
