Please run a few skirmishes solo. Please read the little page the tutorial gave you about traiting your soldier.
We are all very excited about the new toy, and I understand that you want to jump right in with the skirmishes. And big groups are better, right? But when we have a full raid and two-thirds of the soldiers are fresh from the tutorial, those are effectively level 30-40 players in our level 60+ group. That is not a problem on the normal fights, but for anything hard, you’ll notice that the raid is getting crushed.
This is an issue that will work itself out in a few weeks. You can help work it out faster by doing your part. Thank you.
