Conclusion
Overall, these seem like great changes. This has potential to be one of the best patches of this set yet as it addresses many of the major concerns around balancing and artifacts that players have been upset about for quite some time now.
Verdict is still out on whether or not Ashe will be good, but if she's able to return to the meta, then we should see a lot of diversity at the top!
