From my perspective, Jihad is a little bit underpowered. Yes, underpowered.
Most of the TTT maps are wide and large, it makes really hard for traitor to do surprise attack. Traitor dies from it, it has couple seconds timer, noticeable sound, makes the Traitor vulnerable, has a range of couple meters. I don't say, if it gets added we should change anything. It's good like it is now.
'But Mehis, one time a Traitor killed my with a Jihad from 9000 meters!' Well it was probably lag or something.
Though, I still say that Jihad shouldn't be added. TTT is fun like it is now.
Or Jihad could be holiday specific. Just make it little bit more holiday-ish.
