Would be interesting if strike specific gear followed what the solstice of heroes armor did. Get the basic version in regular strikes, and then doing the nightfall version of the strike possibly even getting a certain score upgrades it. You could even do things like kill both tanks in the Bracus strike as a requirement. God help you if getting tank kills is one. It's basically like taking challenges and applying it to armor, but it's still fun to have your armor actually upgrade.
