I have to agree with @Andy_wan_kenobi and others on this one. The unlockable boss feels like a novelty item versus an actual functional playable part of the game. Perhaps it’s because of where my game is at versus say someone that has recently picked up the game. I can go and do regular PvP or MOD PvP until my thumbs fall of because of the amount of creatures I have, it only costs 5/10 DB a match and while one type does have food and coins as prizes on the wheels they do not have a 90% chance of being landed on.
So I can either spend 20-30 DB on a boss battle with a shot at one prize with a 90% chance I am going to win coin or food:
and it is going to take the same amount of time as probably 2-3 regular PvP matches with a cost of 10-15 DB and a shot at 2-6 prize wheel spins with chances of food and coin only being 50% and actually a decent chance of getting something I can use:
Now I am guessing the unlock able bosses are not aimed at your long term players but fixing the the rewards for the length of the matches and cost would go a long way in not making this boss and possible future bosses just become park decorations like their former statues.
It’s also the one thing that you have introduced into the game that I am aware of that you can’t grind towards on your own schedule in terms of resources. Everything else in terms of resources if you are willing to put the time in, you can go grind for, but Boss DNA you are limited to Ludia’s schedule, I mean what better incentive for the boss battles than putting Boss DNA on the spin wheel of the boss battles. I guess technically the most recent SDNA would fall into this same category since it is only available via the missions as well but at least that is something that gets refreshed every day and as a paying member of VIP there is an incentive for that. The Boss DNA has no benefit for VIP members which seems odd.
