@cyoce It's not skill-less, fire support adds another level of complexity onto a game beyond the typical infantry-based combat.
As commander, the placement of fire support can make or break a match. Though I do think that the current commander/observer implementation for calling in support is stupid, the concept of having a player control the battlefield and support the team is an extremely good game mechanic, especially for people playing in coordinated teams once voip and voice chat get fully implemented.
Even in a match with random people, it encourages team communication as teammates suggest or critique fire support calls by the commander. Further, it increases the coordination of attacks and makes sure that every member of the team is focused on the objective and attacking it as a unit. You can't just wander off and try to do everything yourself since you have to consider how the fire support is being placed. If you're not a team player you get hit by the friendly fire.
Finally, the types of fire support realistically reflect the extra considerations infantry units need to take in modern combat. You no longer have to solely worry about enemy infantry and where you're getting shot from, now you have to think about your own survival in a much more open way. You need to consider your cover from the air, you need to consider how to respond to gas attacks. It's an extra fear factor which makes the thrill of SS so much more intense and fulfilling. Removing fire support would relegate the game from being an experience to being just a game.
In summary fire support (1) requires a skillful commander and finally introduces a true high-responsibility role (2) increases team communication (3) increases attack coordination and therefore teamwork (4) is realistic for the modern day (5) increases the modern combat experience offered by Ins SS, setting it apart from other games.
All the extra explosions, effects, callouts, and general hubbub that come with fire support being dished out or received increase the sense of chaos and make the game live up to a simulation of modern combat moreso than just a tactical shooter. I want SS to be as close to a simulation as it can, so yes, removing fire support except for smoke would ruin the game for me, and is therefore a highly undesirable proposition for me. Ew.
