@FunkOff This is a pointless statement. T2 units should always be less mass efficient than T1 and T3 should always be less efficient than T2 when looking at raw HP and dmg stats.
This is because you get better dps/hp density on higher tier units, you need to limit the way it scales.
If you had linear scaling then as Femto has already mentioned certain units would clear be game breaking.
If you are playing a wide open map, how many tmD and t2 pd combinations must the enemy make? For 1 MML you are now making him spend the mass for 4-5 TMD?
This is why on DG Nuke is always netgain 0, because you force 2 SMD which is 15k mass against 15k mass. Which is why its so dominant.
@FtXCommando I don't think TML are that dominant. They cost a lot in initial investment are easily scouted and easily countered. If you're suggesting bombing TMD then i suggest bombing TML. Also you can block TML with a single land fac in construction.
Also cybran shields are cheap.
