Yes it is. Hydran is pretty tough to fly against the Alliance races.
How so? Seems like 6 of one and a half dozen of the other.
The traditional Hydran enemies are the lyrans (wyn) Klinks and ....uh... tholians IIRC....
The ships arent designed around plasma evasion....they are designed primarily for carrier operations....and have power curves appropriate...
And the feddies have the longer range proxie...where a hydran can standoff and harrass a klink with fighters and hellbores....a fed and give it right back.....and the high speed needed for plasma evasion presents a higher risk of loosing fighters if deployed...and those fighters are a good deal of the hydran's firepower...
subtle differences yes....but still differences
I'm not expert on hydrans...just my observations from flying against them so long....
