Quoting Orodum, reply 4eh-em. Vasari should be the strongest. they are, after all, the warfare race (kinda-they are actually the phase race, but their ships are in general more powerful, tho more expensive). TEC is economy race, advent is culture, so the advent being lowest sounds right, but TEC would not have the highest damage value. the whole "millenia of peace" thing kinda deadens the warfare technology they had, and the Vasari would definitely have mine experience (trying to halt/slow the unknown threat) and the TEC would never have had any reason to develop mines.
Ideed how ev er since TEC mine can only be deployed in system you own by buuilded them and payign for them. For them not being able to be use offensively, For Vasari being able to pop out lots of mine for free TEC mines need to be the strengest. ITs a balance and not sotry and feel decision.
Why with Vasari are you even gonna bother Mining an area? The best use of a Ruiner is run it with a fleet and wait for the Subjugators to freeze the enemy fleet. Then when that happens you mine the area around them so when the stun wears off they are annihilated once they move.....
Outside of that mining areas is a long process that takes to long.
