You are right.... of course, I remember hearing a LOT of Hydran pilots on GW2 complain about losing their LB (156 BPV), LC (138), LM (150), & DG's (154) to D5D's (116).... they would have 3, 6 ,6, & 3 fighters respectively. (costs not included in BPV totals)
I would have lost more than the one heavy I did against D5D's if it hadn't been for people new to the D2 NOT realizing that capturing was an option until they had already used all their marines on H&R's.
