Just a perk that could be added to the overlord since we don't get a lot more than HR except a better kit. - Repair ( It won't cost 5k but 2.5k and will have a cooldown -salamander9o) This is a just a suggestion so please no rude comments about my suggestion.
pets were removed because of a dupe glitch, repair would be nice, and spawners we cant do as of the EULA now.
I agree that the benefits of OL are pretty lame vs HR, but repair isn't really needed now that it's fixed in the shop. But hey, support because it wouldn't hurt and OL's need a bit more icing on their top slice of cake.
Support. OL don't seem to get a great advantage over HR for 30 more so I think reduced repair would be nice (and I'm hr not lookin to OL lol)
