Borg Mixed Technology Unit Analysis
Although expensive, mixed tech Adaptors are quite useful for both Directives to combat medium and large sized units. After you capture an opponent’s construction ship you will get the option to construct an Adaption Matrix. Unlike other factions which must research their captured alien technology, all you need in order to build mixed-tech Adaptors is to build the Adaption Matrix. When you accumulate 20 Collective Connections for both avatars you will notice that upon selecting an Adaptor for construction, a new module can now be selected. This Adaption Module gives your Adaptors a 15% reduction in damage incurred by the faction for which you built the Adaption Matrix. In other words, if you build an Adaption Matrix for the Dominion, a fully “adapted” Adaptor will take 30% less damage from Dominion forces.
Since only the relatively cheap Adaption Matrix is required to build these Adaptors, producing "adapted" Adaptors to combat your opponents large and medium sized vessels is quite doable. Despite still only having a graviton torpedo as its basic weapon, the Adaptor becomes more cost effective for both factions than upgrading to an Assimilator, if you are facing the faction whose adaption modules are installed in the vessel. With non-matching modules, the vessel is still cost effective for Optimize, but Assimilate is better off waiting to build an Assimilator. With two Adaption Modules, the base defense of the Adaptor becomes 47, which exceeds that of the Optimize Assimilator, for substantially less resources. It is always better to equip each vessel with two Adaption Modules, as the damage decrease far makes up for the loss of a slightly greater boost in regenerative capabilities and the reduction in torpedo damage. Early, mid-game, and even late game a mixed-tech Adaptor can be very powerful. Mixed-tech Adaptors also retain their avatar bonuses (so for the Optimize avatar, they still have a 30% reduction for cost on the Adaptor chassis). Remember that with their large special energy reserves, it is of the utmost importance to build a Transmission Matrix to allow these vessels to make use of Slicer up to three times in quick succession. Note that an Adaption Matrix will give your assimilated vessels (and allied vessels) the ability to be repaired and recrewed there.
