I ' m assuming that this 4 helions and 8 marines with a medivac hits about the same time as 211 . So your opponent should be able to fend of 16 marines with stim and 2 medivacs at that point . If they are taking damage or even straight up losing to just 8 marines and 4 helions , which arguably are weaker than 16 marines with 2 medivacs and stim , then I think this tells more about your opponents being bad than about your build being good or bad . In the other words your success most likely comes from the fact that you have a clear plan when going in the game as well as some experience with it so your execution is much better compared to your opponents and this is what makes you win the games . Your build itself doesn ' t matter much for this . So you could achieve the same results with pretty much anything , for example if you focused on the already mentioned 211 build you ' d likely steam roll your opponents every time . ' Misc . tip If you continue doing this , then consider bringing in some scvs for repair so you can keep the bc alive after it warps in . Try to keep any surviving marineshelions behind it so your opponent needs to manually target or he will waste dps on the bc .
