Issue 1: 3PV is needed to help new users learn how to control a mech
Solution One: Create a tutorial that explains what these things are!

Solution Two: Add in game graphics that help users BETTER understand the Hud
Option 1 - Beginner Direction Overlay that is toggled like hints

Option 2 - Military Style Iconography (That works!)

Issue 1: 3PV is needed to show off skins!
Solution One: Why not have a 'hero' start up sequence that starts as a camera on the ground and shows your mech entering battle. Ideas could be drop pods that fall from the sky and break open on impact, your mech takes a few strides and turns its torso, then switches to cockpit. Or your mech and teammates are shown exiting a hanger bay with the doors closing behind it.
Solution Two:
End of match you get a 'hero' pose of your mech on the field camera slowly going around the mech.
Solution Three:
Game has a five second playback recorded from 3PV for each kill that is presented as an option to the user to watch or save at the end of the match with an 'MVP' mech selected from your team to also showcase... maybe it is the entire game so you can replay it and see your performance!

Anyways, take a moment to throw out some ideas. Maybe it is too late for 3PV but maybe we can be a community that helps provide ideas instead of just bickers and trolls people
