I think this change encourages the use of autorun, but at the same time it discourages the use of Solar Blast.

Before autorun, I would use Solar Blast all the time. After autorun, I'd use Solar Blast whenever I didn't autorun (20% of the time).
Now, I never use Solar Blast. Because they removed the "click to fast forward", it just takes too long to manually clear a map. Thus, autorunning is the best option, and if you tab away while autorunning you don't really use Solar Blast. Personally I don't find that Solar Blast is worth the time it takes for the animation to go through, so I don't mind.

Solar blast, IMO, is only useful as an aoe nuke against multiple targets (like having a guaranteed aoe proc on a girl). Its damage per target isn't high enough to warrant use against boss-types unless they're just THAT close to death but they're going to unleash a wave of aoe attacks against your girls. Either that or your squads are borderline for completing a map and SB gives you the boost u need to win.
