I'd like to address a few points here that made me feel... Doubtful about Infinite Crisis. Although the game has its own flair, it can, in some aspects, seem really amateurish due to some none too impactful details that just look sloppy. Here are some recommendations for what needs improvement, feel free to discuss and add to the list. I am posting this here, because this is a more popular section and is more likely to provide discussion.
1. The Tutorial
Right now there's only the first mission, isn't there? That doesn't appear to be enough, as the basics of tactical play is not explained. I've had several players in my games who did not know how to recall or how to buy items. It'd be best to take new players by the hand for a bit and guide them through a better tutorial, and start them off in 5vsAI matches. Right now, a new player can feel very lost.
2. Champion Information
There's two completely different info pages for each champion, and they're not right next to each other. The one on your protector profile fails to address lore and doesn't have a showcase video. The one in the shop does not show the amplifier set or stolen power. Make these identical, please. It's senselessly annoying to pong back and forth between shop and profile to get the full image of a champion.
3. The Chat
Group chat is not displayed if you are not in the group section. Chatbox overlaps the left team's bottom two players and thus clutters up the screen. This needs to be reshaped, as it looks unpolished.
4. Loadout Saving
You have to reselect your stolen powers (And possibly amplifier set too, although I'm not that far yet) every single time you enter a match. Change this to where you can save your loadout to a champion. It's a small feature, but something that can really help players feel more comfortable.
5. Skin Previewing
We've got a few screenshots, but I'd rather have screenshots of the new skin and the standard skin side by side to showcase their differences. It can be hard to make a decision.
6. Skin Design
If you want people to give you money, your skin design will probably have to improve. There's quite a few skins that don't feel like they add much. Keep in mind that your standard skins are very iconic, and thus the skins you release need to be extra special to overcome that and entice people to buy. I've been interested in Jade Warrior Emerald Lantern, but the skin didn't seem to do justice to the character and didn't change enough to make me want it. I feel like the standard skin's design was actually a better one.
7. Level Values and Coefficients of Stolen Powers
Right now, tooltips for Stolen Powers outside matches only show the value for an unleveled, level 1 use, and powers like GL's comet drop and Harley Quinn's Detonate do not show their stat coefficients.
