Obsolete CE Guide
This is a simple guide that lists Event CE's that have already had their Re-runs Completed and therefore no longer needed. This guide will continue to be updated as Events have their Re-run versions completed.
Its usually the best time to get rid of these CE's during increased success rate campaigns so you can get the most experience when using them to power up your other CE's.
This Guide will list CE's that are generally not worth keeping around for long term use. However you are free to choose to do whatever you want with the CE's in your inventory.
