Sharing a thought.. The miner and gob barrel placement strategy to trick opponents is not a level play in my opinion. The need to have a higher skill to ensure you as the opponent doesn't fall to this placement trick is not 100% consistent when coupled with latency.

An example is a perfectly timed ewiz deploy dmg hitting all 3 gobs, which even at your best, work 90% of the time with 10% risk of missing all gobs. Likewise, the left/right/front placement of gob barrel to avoid barb barrel is a different level play as the need to counter it is a higher skill of carefully observing the shadow.

Same goes for miner, where placement can be used to player's advantage, but to stop the miner attack totally is a higher skill to by observing the direction and exclamation mark.
