The question on focus… Means little… This is more about HR and how many content developers you have to engineers… There are multi-skilled people but you kind of want to apply the art, effects, zones to the game while developing them to get a feel for if they look good and what your creative team needs.
This lets go fix bugs only thing… That’s not something that’s going to happen. You want bugs fixed you get HR to hire more engineers… Engineers that are likely very temporary because as soon as you get the bugs fixed and developer toolkits setup. You basically have to fire them on the spot or have them sit around the office eating money you could spend on the creative team instead.
