Well this is what I’ve experienced.
My mech pilots are level 13 and Enlist is level 10.
When I play a mech pilot card and use enlist, I receive level 10 mech pilots.
Upon playing these level 10 mech pilots I get a big pilot who is level 13, with one level 10 pilot left over. It seems that whichever pilots are already active on the stage will be used to combine, pulling from the card you just played last (hence why I have a level 10 pilot left in this case and not a level 13).
This remaining level 10 pilot was then combined with a level 13 mech pilot card I had in my hand.
The big guy was now level 10, not 13. In addition, I had one level 13 mech pilot leftover.
Basically, I think the level of the “active pilots” in the arena will determine what level the big guy will be. So if a level 10 pilot is on the board, it doesn’t matter what level pilots are in my hand, the big guy will be level 10 upon playing the card.
I’ve repeated this several times, but I could still be wrong, if anyone else checks this out, please let me know!
Is this problematic ? Well I’ll just dream for the day I can get enlist besides $100!
