Hopefully you have read Part 01 of the Human/Spartan Combat Model (H/SCM), if not please read up. The topic of this next blog will be how gameplay will be affected via this free-form class structure.
Proficiency Based Gameplay:
Ultimately the goal of this mod is to provide players a chance to jump into combat with little to no previous experience of Halo and end up with a character customized to meet their own strengths. Weapons, vehicles, maps and gametypes will all have their own balancing factors. The bonuses that players get from these items only helps to improve their own individual characteristics when using them. What this translates to is that if a player does not use a given weapon/vehicle, expect a player that does to be much better when using it.
Unlike most Role-Playing Games (RPGs) these skills will build up rather quickly. Considering that most matches last 20-30 minutes, you would expect players to gain a proficient level when using a single weapon after a very limited time. This is not to say that higher levels would be easy to attain, but only that shorter periods of time are needed to gain the most basic upgrades.
Example: A player begins the game with a pistol and proceeds to gain a few quick kills. If the requirement for the first pistol proficiency upgrade was 5 kills using that weapon, a player could easily attain it at a rather quick pace. Note that only the killing shot must be from the pistol, so feel free to use any other weapon to weaken your opponent first. After reaching 5 kills the player goes from skill 0 (zero) to skill 1 with the pistol and a bonus, such as an extra clip of ammunition is added to the pistol every time the player picks one up. Keep in mind that these bonuses are quite arbitrary at this point and only the general concept is important.
As a player's proficiency increases with a given item, it would be easier for them to gain that next skill level when using that item. Of course, the curve for attaining the top levels will be much harder than the more basic ones, so the rewards or benefits will be much better as well.
