The gap is 1.5. If your opponent has most 12-13s and you have 11s below it should be challenge in master league but not in tiberium league. Training doesn’t count.
I'm not sure if that's always the case. Look at my attached photos (the topmost game of each picture). My average level is 9.42, so if my opponent's average is 11.0 or above, it should trigger a Challenge Battle. However, none of those are. I don't think the problem is due to my deck as well because when I face a real big whale (level 12+), it still triggers. I think the gap of 1.5 should be large enough. (Maybe even too large IMO). 2+ gap to trigger is absolutely nonsense.
I hope EA can clarify this for me.
Another condition for challenge is your opponent's lvl has to be at least (cap - 1.5) in this case 11.5. Sounds brutal but none of you show has that high lvls.
I know you can get into master with 8-9s but then your nightmare just starts.
