Yes and as I said, war isn't meant to be easy.Good on you. This is not Crusader Kings tho.
People are so used to "winning" they moan on this forums for endless pages how insufferable a rebuy is.
If you really think players aren't running away if they can't have at least small victories, I have an Anaconda to sell to you at Hutton Orbital.
I've also said things will get easier and rebuys won't be as common. The new turreted AX weapons for example seem to be really good against the smaller Thargoid ships and they're also easily available at Megaships and don't need a grind.
