Currently, the mod's roster (for the most part, pending some GDI buffs) feels pretty good, but in playing the mod I notice that on both teams there exists some glaring holes in the selection of classes that I feel could be filled to flesh out a team's options. Now, for an RTS, having glaring holes in a roster isn't necessarily a bad thing, and can be a good thing as players choose (or not choose) which team they want to play.
This, however, is a multiplayer FPS where you are unable to choose your team, and especially for a newer player or a player with a more limited skillset of which roles they are good at, this can be a pretty bad thing. In the spirit of keeping asymmetrical rosters I'm not suggesting anything that would have the teams mirror each other, but for the sake of standard team play and those dynamics I do feel some vital, basic roles should be filled to grant both factions an amount of flexibility that allows them to be played differently depending on the players of that team and the mood of those players.
I also understand this is not IA. I'm not, and never will, ask for more than what I'm asking for right now. I just feel that, especially considering how Harvesters, MSA's, and Mobile Stealth Generators do not offer compelling gameplay on their own, that having one or two more options to use would help flesh this game out.
A lot of these are just suggestions/ideas, and honestly I would never expect recreations of them. If any of them are listened to, your interpretation or use of them is entirely up to you.
