Well, I've sat through half of your video, and have learnt nothing. All I see is a "L33t Montag3" of nitpicked shots. I'll struggle through it after writing this.
It also doesn't address the overwhelming downsides are part of the Nova. Terrible construction rules, some of the worst hitboxes in the game, and rather poor hardpoint placement.
Shall we make a quick Smurfy to discuss the construction rules?
Here we have the Nova:
TBT-NopeVa
Swap that to a 255 and gain a Kph for nothing.
Go to a 280XL with Endo and gain a ton of pod space, at the cost of 5 crit slots (engine DHS slot, save 2, Endo costs 7)
Nova-280
But wait! Change that to an XL300, drop a single JJ, and suddenly you've lost a half ton of pod space, while you're now moving at 107! That's with 4 JJs and it only cost you 2 crit slots, since you've saved 5 from 2 DHS (now in the 300 engine) and lost the CT JJ.
Nova-300
The Nova itself can pack some weapons. It can do well...as long as you're never seen. As soon as someone has seen you at 300M, you're royally screwed.
I have a love hate with the chassis...sometimes I take the 10-12 laser builds, do well, then get that one terribad match and get ganked at 400M without being able to touch them. Then I swap to the 6 ERML build, do well, then get that one terribad match and get the arm Penta Gaussed straight off. So I grab a 12 laser build, etc....
It's far too large, it could be designed far better, though at least it gets 10 TrueDubs.
There are worse robots out there, this one is salvageable, but it's got far too many downsides to be taken seriously. Those stem from mechlab restrictions and the physical attributes of the mech.
It's a good glass cannon, I suppose. It can be a fun robot, and an infuriating one.
