the thing who is nice with autowarkeys is that u can enable autocast very easely.
For example, with morphling, i enable autocast on morph by pressing alt+z or alt+e ( z & e are my hotkeys for morph str and morph agility )
Its really faster than use right click on it.
At the contrary u cant have macro with autowarkeys ( tell me if im wrong )
WIth warkeys++ however u can set 3 macros.For example in mine, i setted 3 macro i use with invoker
F3 = i set my power balls for ghost walk
F4 = i set my power balls for tornado
F5 = i set my power balls for ice wall
so i click F3 then i use invoke and i get ghost walk in my skill panel
Btw u can run warkeys++ and warkeys at the same time, so u have to chose.
For my part i use warkeys++ for all heroes except the one who can use autocast(morph,destro,bone,puck etc).For them i use autowarkeys
