hm, talking about meta: I wouldn't consider shock rifle non meta, especially not if you spend all your fuel on a dozen of is2s
many people loved ShockRifle and it has already proven to useful commander.
however I think that commander needs some condition. it is a good start in the early game and u should be able to prepare the tier 3.
why does dbmb got win the StarCrossCup(of course, I still think Giap is better but dbmb is the winner). he is the one who adapt early on the meta. he selecting the Guard spam, using Ostheer sniper in the early game etc...
well I mean, Guards is the best selection on this meta. gg wp.
