This is something that came to me just now as of this post, A tech base that instead of being uber like the clans. Specializes into Weight and crit reduction for their weapons and equipment in general. They may not damage or shoot as far as the clan weapons, but they are significantly lighter and less bulky than their clan or inner sphere counterparts. Let's Take this tech bases Medium Laser as an example.
In comparison to the IS medium laser, this tech base's medium laser weighs 0.5 tons and takes up only one crit but the other statistics and characteristics are the same as their IS counterpart. Similarly is the case for their ER Medium Laser(0.5 tons and 1 crit). Making them desirable from at least a tonnage and bulkiness front. the main drawback would be cost(as the tech needed to make them is classes as E-F rated) and heat generated is 25% higher than normal. Meaning this tech bases ER medium laser generates 7 points of heat vs 5 points for clan and IS counterparts and likewise 5 for the standard version.
Overall I am still working out the main drawbacks and advantages of this tech base. But their Endo-Steel and Ferro-Fibros armour takes up 4 crits vs 7 or 14. Similarly their XL Fusion engines only take up one slot per a side torso vs two or three per a side torso(but generates double heat for movement 4 vs 2 for movement).
