I bet someone else somewhere else mentioned this (but I could not find it, so I will start a topic), but I would love to see the possibility, to run older 60 Content like Alexander or the Primals with all Skills, but the Stats synched. To revive at least a Part of the feeling of the old days.
The Devs removed a good Number of Skills from the Hotbars and some Classes don't feel right on Lvl 60, but I bet people would like to play older Content like Alex Savage or the Primals again for fun.
Unsynched is just not filling this Gap. Punching Zurvan down in 30 Seconds feels just empty for me.
