I recently helped out a kin to level up so we did a tier 3 lvl 65 skirm. I used my lvl 78 warden. My question is, when i looked at my skirmish soldier it says he's level 78 but i know that i only leveled him to level 60 with the skirmish trainer. Is this a bug or does it just show it's level 78 but functioning/damaging as a level 60?

I would really appreciate any clarification on the matter. Thank you.
