So do you think the Cannon should be not be changed from its current form? Also, im curious as to what you think of the SKS cannons from P9 Megas. Do you think those are overpowered?
SKS? P9? The only faction mods I am familiar with are Blackrock and Templars (and a few other dead ones). I usually play mod-less standard.
The reason I use Sentennia in a heavy slot is because standard heavy energy weapons are weak enough (as of 0.65) that I prefer Heavy Blaster over all of them unless I desperately need the 700 range from plasma cannon and I have no better alternative. (For example, I use plasma cannon with Apogee, but I use triple heavy blasters with Sunder, and capitals get heavy blasters in all heavy mounts.) Similarly, in an earlier version of Templars, their heavy weapons did not outperform Sentennia enough to justify using them over Sentennia. For example, why pay 20 or more OP for a heavier weapon that outperforms a powerful medium weapon by say... only +25%?
If I prefer Heavy Blaster over any heavy standard energy weapon, and I prefer Sentennia over Heavy Blaster in every situation except in a rare Hyperion vs. Combat 10 Paragon or Doom matchup, then (of course) I want to use Sentennia. (I will still keep a blaster Hyperion handy to counter pesky Paragons and Dooms.)
Juger used to be awful; now the arcing is truly murderous against small stuff, and direct hit is painful. Joyese ran out of juice over prolonged battles enough that Sentennia might have overtook it, much like how Heavy Blaster overtakes Autopulse Laser in about six seconds.
Hyperion is not the only ship I use Sentennia. I use it on every standard and Templar ship with medium energy mounts except Tempest (because it cannot support two without giving up too much). For ships with medium universals, Galatine may compete because forcing overloads is powerful. As for Paragon, it has enough OP to indulge in heavy Templar weapons. A properly outfitted Paragon with Templar weapons can kill the entire simulator fleet (deployed as much and soon as possible) before running out of CR (but it is hard... so much ships).
The last time I tried the Sentennia, after it was nerfed, I thought it is was still very powerful. Despite not being all-powerful, range and homing still made it very powerful. Most importantly, Sentennia enables high-tech ships to kite.
