CM is a video game and like all video games, balancing is tough.
Especially when it comes to a game where you play with -and- against OTHER players.
It's up to us as the players to voice our opinions, give suggestions and hopefully you strike oil with those things.
From what I can see thus far, Xenos are extremely tough to kill when it comes to a....let's call it a "fair fight". They have great utility and once teamwork comes into play, a few Xenos can easily dominate the field together.
This tips the combat scale too much in one direction. The marines need more utility in game mechanics to help them stay afloat or at the very least create more interesting situations.
We enter the game and it starts off at a 0. Eventually the climax builds up and the arrow begins to move up the chart and eventually plateaus mid-round until the very end where the Xenos overtake the FOB and eventually boards the Almayer to clean house, the flat-lined action then steadily drops down on the chart and we're done.
As of right now, we have a game where marine players get geared, get a little RP in with each other before being briefed on objectives by other players who assume Command roles, and then they're dropped into the what I call the "gameplay zone".
In this "gameplay zone" is where the action happens obviously and RP is scarce or is reduced to quick snippets once the fighting starts.
I don't have too many ideas as how we can make this better but one idea I do have is something like....
Perhaps things like random events that occur mid round? They can be Admin-created or perhaps timed events. They can vary from colony to colony.
These random events can take the attention away from the Humans vs Xenos for a little bit and force the two sides to react to these events as they fight eachother. (I.E. A volcanic eruption on Big Red covering areas of the map with impassible lava or on the Ice Colony, there's suddenly an earthquake and certain parts of the underground areas are collapsed.)
These are boring and cliche examples, but you guys get the idea. This is just one of many suggestions out there to create a more dynamic "mid-round".
