This is a very versatile build - although it lacks stealthy weapons, its a great skirmisher and loves the PUG queue where you stick to the edge of the pack and whittle down the enemies. The LB10x is light at only 11 tons, but with the Ballistic Cooldown of 15% Quirk gets DPS of 5+, it also runs cool, allowing the use of ER-MLs. With Stealth armour if you need to sneak, a speed of 100Kph+ (skills) a couple of JJs, and a pair of Arty strikes, there is very little this mech cant do!
If you are not going to brawl, stealth is almost useless. The main feature of stealth armor is to prevent lock and targeting below 270 meters (unless your stealth will be disabled by a PPC / NARC / TAG other). If you expect to shoot over 270 meters most of the times, there is no point to use stealth armor over standalone ECM: the 1.5 heat/s malus and wasted slots / tonnage aren't really worth it. Non-stealth version with AC10 is slightly hotter but has way better pinpoint at range.
yeah i agree - almost useless, but occasionally prevents locks from BAP and direct LOS locks the worst thing is the loss of sensor range.
Actually stealths purpose to dissapear when someone spots you, run round a corner, brace against a wall, you need to use 2x Seismic sensors, if someone comes within 200m on Seismic you can either Power Down which is risky or engage Stealth. This is the way of the ninja.
