Couldn't dis-agree more. Ion Bolt is the only truly useful general combat ability for the Akkan. TU has only the most MARGINAL of uses ie out ranging a SB and Armistice is situational only. Lets compare that with the combat utility of the other Colo Caps.
Nano-Dissembler- widely accepted as the single best sniping ability in the game. Chews through cap ships like they are breakfast.
Gravity Bomb- Similar practical effects to Ion Bolt, doesn't completely shutdown ship but slows them substantially and prevents phase jump and with an uncapped AOE with decent area size. Can shutdown whole fleets of clumped ships from leaving for 18s at level 3 and fire again in 7s.
Akk vs Evac- L3 Ion Bolt can keep 1 ship shutdown with a net 7s cooldown and L3 Grav Bomb can keep "infinite" ships from warping with a net 7s cooldown. Hmmmm yeah Ion sounds REALLY OP in that context..... Evac gets the win on this comparison
Progenitor: Harder to compare as it doesn't have a "shutdown" ability however;
Shield Regen- Huge fleet synergies especially when paired with guardians. At L3, recharges 500 Shield pts in 8s on infinite ships with 12s net cool down.
Malice- Turns ordinary attacks in AOE. Been nerfed pretty badly so not overly useful, can still synergize with CB to spread some pain but not to NEAR the extent it once did.
Akk vs Prog- I deem this a tie. Ion has far better combat utility than Malice but Shield Regen is leaps and bounds above Targeting uplink in terms of fleet support.
So in my opinion Ion is about right, TU needs a buff. I think a slight bonus to damage for those affected by Uplink feels right both from a utility and lore standpoint.
Evac is spot on.
Prog could use a slight buff to Malice trying to get that sweet spot somewhere what the ability used to do and what it currently does.
Point is, Ion is fine.
