Here's another interesting twist. Look at what Sdub says:
Got this quote from the Classic server thread. It may help you get some Expirience points.
Another benefit of Classic Mode is that it gives you experience for all your suit modes, Stealth, Armor, and Power, in relation to how long you played in the Classic Mode server. So, if you ever wanted to switch to normal server you could, and wouldn't be short any experience in those categories.
Experience in those categories levels you up and allows you to pick other modules. For example, Visor enhance in the stealth category requires level 6 Stealth to use. So, playing in a classic mode would get you experience towards that progression.
This may work well for the new players as well. Running Terminal in IA with another small map, 24/7 could be of help.
