I think here you're devaluing the individual troops because they are in a fireteam. Not only is this a perspective that prevents you from fully utilizing a link, but it ignores the "weak link" problem where losing members loses bonuses. Having alternate paths to remove the fireteam bonuses makes them easier to pick them apart. For example, Massacre getting one with an e/m grenade? Not a big deal. Massacre getting the Missile Launcher so they rest of the link loses their BS bonuses so my second combat group with a Hellcat HMG already positioned to outrange them with 5 orders left? Their weakness drastically increases my chance of devastating their link with combined arms. Most HI were bad, especially links. Some were fixed. Now new, already competitive ones were added. Brigada got powercreeped in category, but that was hard to avoid.
