I disagree on the Endurance Part. I set it with Marauder every TW (Negotiator can still exist without Marauder or Fives) and it is getting a crazy amount of Holds. I set it this way because not a lot of Players know how to handle it and thats its strenght. There is barely any Data on it, so it gets underestimated and they throw something too weak at it. Keep in mind, i am in more of a Mid Game Guild (roughly 390 Mil GP). I think Endurance is a really Strong and Underestimated Capital Ship and only needs that little Something to be a really strong Ship and just outshine Negotiator, mainly because of the Ult which is probably like the 4th best ult after Exec, Prof and Levi. Its just an I win button, you get all that Prot Up and Bonus Turns which trigger TM for the Endurance and it will just ho crazy and win.
I hard disagree on the leviathan argument. Sure it’s expensive but if your guild has an advantage in terms of leviathans unlocked, it makes the defense and offense planning way more flexible. My guild has won war purely based on our 20-ish leviathans holding the zone while we can clear our opponent’s fleets. I think the benefit of that fleet far outweighs the cost but that’s just my opinion. Very informative video overall!
