Hello 
Just to say that I lol’d hard at " Who needs medics with a spawntime of 10 ". Everybody knows that 10 seconds is huge, and medics also mean sustain for a team, hence the choice of many teams to play with a lot of medics in the enemy territory game-play. A team can afford to lose a player for 10 seconds only from time to time, after a big push/full pull, after an objective (and still, it is not always right since in many case the whole team must rush the next obj in order to take the best positions).
I really don’t know if we should increase the spawn time or not, but the objective/tactic is the soul of Enemy territory’s gameplay while the medic part is its body !
Ah, and if I have a room to state my opinion on what competitive gameplay here, I would say that on the one hand public gaming is more or less playing at war, as some of us may want after seeing an action movie or whatever, getting as much frags as possible etc.
On the other hand, competitive gaming is more like a sport : it is a performance (it is not called eSport by chance) with players who have a common interest and a common view of the game. At a very high level you can clearly distinguish team’s playing style, like in rugby or football, and what makes the team really strong, aside of each player’s skill.
In my opinion, ranked is like " player A’s skills " + " players B’s skills " + " players C’s skill " etc. While competitive gaming is " player A’s skills " x " player B’s skills " x " player C’s skills ". That could explain why some teams look quite equal regarding at the players, but the difference of performances appear to be a huge gap, and this gap can be bridged only if the given team practices a lot.
All in all, the difference between public and competitive gaming is a matter of minds, some just want to frag like beast and some want to go further. It is the same difference as playing football in the street with your mates and playing football in a club. As when you play in the street you don’t need special shoes or a special field, when you wanna do public you just want to join a server, take your favorite class with your favorite weapon regardless of your team’s need and destroy everything. Making a balance for public regarding to this fact is one thing, and making balance for competitive is another.
