More Bosses in Boss Battle and More Crests

Can I request for us to get more Bosses in Boss Battles, there is a very limiting amount and I have plenty of boss battles and have to reuse the same boss, which I don't like.

I know it is difficult as you have to get your artists to draw a boss, but in 3 years you've only added 3 new bosses. Can this be made a priority, you only need to draw the one image and the kids love seeing the different types of creatures for the bosses. More choices would be wonderful.

Furthermore can we have more crests for teams, I know custom crests is a long way for happening, but more crests would mean more options for students which they would love, again it is only one image to be drawn but I know that still takes time and paying an artist, but I think it is worth making a priority.
