Looking at Utility Workshop adds for SF and I don't really see any significant advantage to any of them... they appear to be more of wash between the advantages and disadvantages for all three - Orders, Loadout and Defense.
The obvious one is the Order workshop... what you gain in the first 50% you loose in the later 50% of health.
The Loadout slows fire rate and increases reload time... but, no additional health or added range to compensate.
The Defense reduces damage (or caps it on the first shot) ... but, slows the spread... and more importantly that would make the ability to use the unit offensively much less valuable.. thereby cutting the value of the unit in half.
And... of course... ALL of these workshop additions will cost more in space and repair time... so, the incentive is to spend time and/or money to add work shopped changes that seem more of a wash in their value... Plus, added future costs to using the unit.
Am I missing something... or are these upgrades worth the trouble... or... (what seem to me)... just a buff that Kixeye is trying to charge for...????
