It goes beyond that, the Bug 'Mechs are poorly designed and poorly conceptualized. Their way too light to carry any worthwhile amount of guns or armor, never mind both, and the entire idea of a scout 'Mech is stupid, a major part of the role of a scout is not being seen, something a two story 'Mech is not very good at.
Play a Clan unit, a 1,000 lb gorilla bumbling around the strategic map, and find the enemy without scouting elements. When you do, it will be on the enemy's terms. BT was conceptualized around having no infantry or vehicles -those were afterthoughts and if you have played long enough, the rules have finally caught up to the reality: Mechs no longer rule the battlefield. They are still powerful, but no longer all-powerful, as they once were.
Double-blind helps, but the idea of using scouting forces in any sort of table top wargame in fundamentally flawed, because the mere fact that a scenario is being played tells the opposing player that you have forces in the field. In the RPG things are better, but things should simply be reduced to a few rolls and nothing more.
I've played out a recon scenario where the appearance of a recon lance just to locate and count the enemy's numbers sent the enemy commander into a panic. He thought he'd be pounded by artillery and dispersed his units, dismounted his infantry to dig in and prepared for a field battle that never happened... My recon lance observed the enemy for the two hours it took for them to realize that they weren't under attack and shadowed the unit until they reached the series of prepared ambushes in their path.
The OPFOR commander had no clue that he was only encountering a recon lance, his briefing gave him an idea of the forces defending the planet and a town to secure. The GM made the scenario for the light lance members to practice, and participate in the merc contract, other than by making a few rolls and doling out experience at the end of the contract.
None of the recon units fired a shot. They stayed well out of range and once the enemy was close enough for the Long Toms to reach them, the recon/scouts did what they did best; they stayed out of combat.
Recon isn't just running around and looking for stuff. If you are ahead of the main body, you map terrain features, river crossings, etc. You locate and mark minefields and occasionally, you may encounter dug-in forces, which you also report. If a recon unit encounters enemy recon elements, their job may become screening: Prevent the enemy from locating, counting and reporting the main body. Usually, its a stand off, with the enemy recon backing off, but aggressive recon units may want to get past you and you may actually have to fight, which is rare, although mechs like the Hussar shine in this instance. Despite its fragility, its speed and offensive capabilities boost its ability to survive against mechs of similar weight...and this discussion is about what survives.
