Well I had the hint of a feeling that I wouldn't get anywhere entering this argument, but what the hell, I've already made the attempt, might as well finish it off properly.
Most of the times I have been in a fight, other than versus AI, is when someone who outmassed me two to one or more, in what I would usually call a newbie brick.
Yeah, this is what I am talking about, this right here.
New players who have little to no experience on how to build a good ship, who have yet to find out their fighting style are going to only learn through browsing these forums and online experience. When you scrape off the cream, the details, all it comes down is personal skill and how fast you can learn.
They lose a fight, learn from it and/or browse starmade forum for how to build a better ship. They try again and hopefully this time they come out as the winner.
Introduce your tier-system and no matter what the new player does, they will without a doubt get their shit kicked in a fight with a ship of equal mass or less and unless their opponent is a utter buffoon, they have snowball's chance in hell of winning. This problem just quadruples in scale when factions of players are thrown into the equation. First and most active factions get established and then stay established by attacking any faction that grows past a certain treshold a la Shores of Hazeron-experience.
If you have such godly resources to so casually throw around, then you already have the ability to "steamroll anyone anywhere and anytime".
Except that everyone has access to the same systems and materials and it all comes down to skill, ship design and doctrine. It doesn't matter if it's new or old faction on the server; if they know what they are doing they can stand up a fight against anyone.
