Sorry, but the reason why SC added another Laboratory is because that you just need to manage and think carefully on what to upgrade. If there where two labs troops upgrades would be easier but it's TOO MUCH. Thanks!
I think two might be a little much.
However I can understand newer players frustration looking at the time involved to get maxed troops when there are now so many players 12 to 18 months ahead of them.
Some early buildings and lab upgrades could be faster - but still cost the same amount of resources.
Players would still have to work to get them, but wouldn't be so permanently disadvantaged.
