I figured since I'm more experienced with the light armor than the other two, I'd take the time and fill out all the questions for this class in my own opinion. I'm sure others' opinions will differ, therefore please add information, and don't hesitate to correct me.
What are the advantages/disadvantages of being this class?
The obvious traits of this armor are portrayed in the name. Light. With only 75 health and very little armor, its not made for 1 on 1 firefights. It can pack the most implants, and its the only class that can stealth.
How many of this class should a team have at any given time?
I strongly believe that the number of lights should change per objective. If you're assaulting a spawn point, say middle span in vaccine, you're going to want 1 or 2 lights to go in after heavies and mediums, for hacking purposes. Other objectives, for example the data storage in fortress, would require more lights; not only for stealthing in, but for hacking.
What is their ideal role in offensive situations?
As offense, they have great weapons, great mobility, and stealth. Tack on some leg boosters with stealth for a great effect. Greatest(in my opinion) class for capping.
What is their ideal role in defensive situations?
Early detection. No, not what you think. I'll use fortress as an example. Say those punks get the firewall down, most of the heavies should switch to lights for 2 reasons: cyberspace defense and the dreaded "EMP the enemy deckers" tactic. Of course renegade lights with bolts or shotguns and stealth is a great tactic to slow down people, as it makes them get thermal goggles and waste energy. Also in the
TG server, with FF being on, thermal goggles make it hard to distinguish between friend and foe, so you raise the chance of enemy TKing.
What implant + weapon combinations are ideal for this class?
Oh man, the possibilities are endless. I mostly use a datajack/thermals with stealth/sound suppresion/SCS. It honestly depends on what your role is.
How can this class interact with teammates of the same class?
Raiding cyberspace, stealthing into objective points. EMPing deckers. If you get 2 lights stealthed in the reactor room in fortress before the enemy can even spawn, slashing the glass and even the reactor takes no time.
How can this class interact with teammates of a different class?
Well, as I said before, light means light. If you're decking and trying to take the enemy spawn with only another light or two, a few grenades or a spider will quickly show you up. Now, if a heavy were standing right at the door, and/or if a medium was on defense with a mediplant, it might buy you that extra bit of time.
Finally, I believe the most important thing for a light is communication. If you hack the turrets and your team doesnt know, you did nothing. If you're slashing the reactor and know one knows to back you up, you did nothing(well unless the enemy team is REALLY slow).
And that's my opinion right there, let me know what you think, I'd love the feedback.
