It would be nice if there was more focus on bug-fixing.
Edit: There are ways to improve code quality. However they come with costs.
1. Code reviews: If a Dev is doing something he's worried might break things, or working on a part of the code base he's not familiar with, get another Dev to look over his changes. However this will slow everyone down.
2. Automated functional tests: Every time there is a crippling, show-stopping bug (example: remember the time a hero died mid-battle and broke the battle script?), add a scenario to an automated test script to make sure that it never happens again. Run the test on every code check-in. However it's insanely expensive in engineering time to create and maintain the automated test script.
