New Game mode needed

You know what I look forward to every midnight reset? To play galactic war. Of course, the crystal refreshes, new challenges, and what not are great and all, however, these are all SIM battles. There's no actual gameplay... Even if I wanted to battle an already 3 starred LS or DS node, it's the same enemies every time. I'll just SIM the battle and get my gear. So there's squad arena right? Well you can only use your best squad otherwise you'll lose your rank.

So, the only time we are forced to battle is Galactic war. You can test out weaker characters and different squads out. I've asked others and most agree, GW is a treat.

For the interest of the community, can we get a new game mode? The key idea is to not allow it to be SIM'd and provide a variety of difficulty like GW. Any suggestions to a new game mode with good longevity?

PS: Ships are a nice addition but I think we can all agree the game revolves around character battles...
