Re: Three suggestions to improve the game
I'd have to disagree about a well-rounded deck being a bad thing. That's how every RTS is, you have a unit counter to everything. The whole point of an RTS is having better tactics, not a better unit lineup for the entire match. While putting pressure on your enemy's economy is a valid strategy to keep their heavy hitters out of play, it shouldn't be the only viable counter. We're playing a Real Time Strategy game. I get that there are limited technical resources due to the platform of the game, but that doesn't mean that strategy ought to be limited like that.
I do think that @PremierVenoth has a good idea though. Being able to have a backup unit or two to swap out would be a nice compromise. In a way, there's already some precedent with Seth's Drill Pod.
