Your wildest hopes and dreams for the game

I see threads every now and then about things that would ruin the game, and while those are fun to discuss I also think it's exciting to dream about amazing things. I know lots of these will probably never happen, but what are some things that you'd put on the top of your list for improvements to the game?

For me, my first choice is an easy one; introduce some other way to merge units. I've been playing since day one, and in the past couple weeks I've found myself not pulling nearly as much on the new heroes banners and mostly pulling to get more copies of my favorite units. My barracks are just about full, I have units that are great and which fill every niche, so I'm mostly only pulling on new banners if there's a character I really like. I've started merging, but my favorite characters are all 5* locked and as a f2pbtw it's slow going. ALSO it's a little frustrating that the original Askr trio and the GHB and TT reward units will basically never be competetive at the tip top levels of the game unless another way of merging is implemented. I don't know precisely how it would work; maybe it could cost orbs, or maybe there could be a new item you only get by sending 5*s home. But there's lots of options.

Another pipe dream of mine would be a make your own banner event, mainly for the reasons I just posted above. But it would work for everyone for different reasons. If there's someone you want more merges for, put them on it. If there's a unit you've always wanted, put them on it. It'd just be fun.

BEFORE YOU SAY ANYTHING I know neither of these are likely to ever happen because they would lose money for IS. But that's what this thread is for. What are your wildest dreams for the game?
