I don't think that's right.If you read the protections window (like the one I've attached), and have it set as I do, you'll see that the way I have my protections setup means that I should not be casting any skills (genie or not) on other players. The protections prevent it.
I can confirm that it works identical to the way it does in PWI. About your point on using it, if an archer is attacking you it's wiser to use AD instead. If you don't have time to click your portrait & then expel then the lightnings will finish you anyway. Since clicking it takes no more than 1-2 hits worth of time. Making it self cast would be a bit of a pitty (saving healers etc from sins in mass pk with it is quite usefull.) but since the majority just uses it to try and seal others or for self use... yea I guess that would work. Or maybe just extend the range to like 40..., but that would make the unintended-usage seal other thing even stronger.
On a side note can sins maze step + expel ? physical immunity without being silenced - cuz maze step make sins unable to be stunned or immobilized and it should also have same effect on silence never tested it - that would be a great way for them while fighting other sins seekers bms barbs archers
god people are stupid sometimes....... Expel: works on yourself when you have your protections on or the opponent has their protections off. If the opponent has their protections on it will not work. Think people its really not that hard.
It's hard for the majority, apparently.
I have been having problems with this expel for ages.
