Well this is mostly an overview about my experiences with factions. Also you may find some thoughts about them. What do you think about them? Playing on difficulty 2. It may have influenced my experience.
Humanists:
As a minorfaction they are fine. They aren't especially dangerous but aren't on the squishy side either. A good mix between the troops more often then not.
Spartans:
I am perfectly fine with the spartans as well. They fitting in just right. Lorewise, lootwise and so on. They are easy to beat but then again the loot isn't that great as well. But good in the early months. Also they are quiet destructive and beefy considering they are a minor-faction.
So thats it with the two early factions one most likely will fight. Lets continue with the more advanced / rare minor-factions. (At least from my POV)
Raiders:
Not to say much here either. Considering their place and role in the game they doing a good job in my opinion.
Reticulans:
Quiet squishy. Then again it just fits considering the lore of them. They are feeling right just as well.
Ratmen:
Uhh... I somehow hate these guys. They scare me. I do not know why. They aren't packing a punch but their numbers... their numbers. I tend to flee when I have to face them on a terrormission.
So I guess good job there.
Demons:
Can't say too much about them. But they are quiet scary so far.
Deep ones:
Again. But I do meet them even less then the demons.
Government:
Uhh why are you reading this. You must not fight them.
Smugglers:
Free great loot. Nuff said.
Well, onward to the faction I have to deal with the most. Not a surprise, considering they are major-factions.
Mercs:
Not a major-faction lorewise but boy. These guys are scary. I do not want to mess with them early. So I guess they are fine.
Church:
A difficult faction too evaluate. On the one side their weaker units are a pushover. Things start to get nasty with beastmasters and the other highranked units.
Overall I think the weaker troops could need a buff ore a matron / priest more. The troopmix on better ships, especially if there are exalts, is scary enough. Then again a church is mostly civil though, isn't it?
Academy:
They are more squishy then the church but early on there are much more Osirion which aren't on the squishy side. I think they are more dangerous and their scaling (troopwise) is better.
Feeling right to me. Do not know. The high number of Osirion-Guards counter the squishy low and mid units quiet well.
Stargods:
In my opinion they are fine. The Stargods themself could be a little bit beefier though. Just a tad. A tiny bit.
Guild:
They are just of the chart. They are weak, squishy and well just way too soft. Sure they have Marsec but... Lets not talk about them for now. G.O., Rep and even security all share the same squishines. Do I have to mention the sailors and Engineers? Well Engineers are okay to be honest, considering they are Engineers. But Reps aren't. Then again they are Reps. And traders. So they should be fine. And they are lorewise, yes indeed. Also while on the squishy side you can argue: Thats what Marsec is for. And you are right. Operatives and especially Bodyguards are scary. But where are them? Where? Well to be fair: Bodyguards are fine and their numbers feeling right.
But where are the operatives? The lack of them on most Traderships make them total pushovers. There is almost no danger engaging this ships.
While beeing quiet satisfied with most, if not all, the factions I have one
suggestion: Throw in more operatives every now and then to make the fights a little bit more interesting. Right now the guild are pushovers. If there isn't a rep on a tradeship at least. Which means Marsec.
I think some more operatives would make the fights a little bit more interesting. At least at difficulty 2.
Yeah you can argue that I should increase the difficulty but then again I would adapt. And Operatives would lack again on ships I consider mid-tier. Like Cargofreighters.
Just a few thoughts. What do YOU think about the factions? I am eager to read your opinion.
