I've been thinking about the idea and well... Ultrabright is already better than Dawnblaze and shouldn't really be buffed.
Before you think I'm just here to insult you, you have to consider that energy weapons have an edge of "damage stacking" over heat weapons. Dawnblaze may have 9 resist drain and higher damage output, but Ultrabright can increase its damage by that 116 drain when against a drained opponent, making it hit up to 444 damage, which is more than something that Dawnblaze can do without the help of armor breakers.
But if I were to suggest something to help energy, it would be the removal of energy-free physical items. Why? It's because physical is the main center in between energy and heat, where items require energy and generate heat when used. However, energy-free physical items like Distance Shredder and Rock Polisher have ruined this idea by bringing us a META where physical builds can negate energy use requirements and still shred their opposition.
Yes, physical does have energy-free weapons like Mercy and Annihilation but they're held back by their heavy weight, something that the newer energy-free physical weapons lack.
If that doesn't appeal to everyone, I would also suggest lowering the effectiveness of dual modules because come on... These new METAs are literally orbiting these new modules and are completely dependent on Fortresses and Quad Core Boosters to protect them from boilers and drainers alike. In my opinion, I just don't think it's right to shut boilers and drainers out while giving damage builds the right to reign.
Otherwise, what's the point of being able to use weapons like Corrupt Light or Hysteria if they're just gonna be shunted by builds with 300+ cooling and regen?
