I don't know if it will help you a lot but there is solution to delaying skills. You can put your main skill then put something with very long reuse like Assassin transform then Pirate transform (and if you want you can repeat it 2-3 times). Auto hunt will go trough all skills and you will have delays.
I have more practical solution: -dont use Acumen, if still not sustainable go -wit. This did the trick for me
Thank me later - same for mages, find your best pattern - or remove bers/acumen as advised (for mages)
Oh nvm Body to Mind shows it can be looped once you learn it. They don't put it in the description anymore. But the SE skill can't.
Playing Overlord atm, best way for me at present is life drain & power break on auto use, steal essence takes too much mana and time, i have been afk for ages now and still full hp bar and mp, still think that right click on my many macros would be better though. so for PVE that works great for me, you just gotta find your own formula atm I think.
