Item Sets Request

This is going to sound whiney (it probably is). However, with taking away item sets from the new client. That is whatever. I found a way to fix all of the item sets (it took a LOT of work) to add Redemption and Knights Vow into my sets across all champions since you added them after I started the legacy client. I had an issue previously as well that my Jungle itemset just up and disappeared on me. That took roughly a day to resolve, and it seems that after starting the client again today.... My jungle itemset is gone.

If you're going to take away the itemset builder, could you please at least leave things in place so my itemsets are still valid with whatever format changes you are making? I hate doing this over and over.
