A better way to handle Additional Content (Destiny)
I've always felt like raising the level cap was a bad idea. The issue with upgrading exotics (and who knows where legendaries will fall), is but one symptom. A better way would have been such:
Keep the level cap. Keep 300 as the max upgradable. So how do you then make the new gear valuable? Simple. Your new content, the raid, strikes, and story missions, should have challenges that fit in with the new weapons. So the new stuff is hard with current weapons, but the new ones have characteristics or abilities that make them more desirable for these activities.
There could be new perks that interact in beneficial ways on the new content (for instance, oracle Disruptor, although not something that narrow and specific). New enemies that are best taken down with a void hand canon or void scout rifle? You've just made a new item desirable.
The problem now, is that even for the old stuff, the new weapons will be better by virtue of more attack. This way, it better preserves a place for each and every weapon, and never invalidates anything you've spent the time upgrading.
Catch my drift? The challenges should diversify, but so should your tools for conquering them.
