I'm sitting here on level 12 - level 13 for most of the building skills and it's getting tough to advance them. Mainly due to resource restrictions, ore in particular. With battles coming up next month, i think advancing all the building skills as well as a number of ship skills won't be possible in time. So what are the trade-offs?
With the bunkers providing little protection, i think it's going to be really important to have a fleet up and running before battles are launched. A fleet to discover more planets would be also really useful in alleviating the resource bottle neck as well.
