Biased post because I just hate having my intel permanently stolen by silencer.
But I think my suggestion has merits. Basically I'd make silencer steal 5 intel per kill, but all that intel is returned when silencer dies.
- Feels less oppressive, there's always a way to gain back the stolen intel (just kill silencer), there is always HOPE, it's not gone forever
- At the same time silencer steals much more intel if he doesn't die, so if silencer plays super well (never dies) he can quickly rack up a lot of intel and have a lot of fun (until he dies)
- And best of all: fits his theme better because stealing 5 intel may actually cause enemies to be unable to cast spells even at full mana at some point, which is the ultimate form of silence. Stealing 2 intel is just really annoying but will never reach a point where an enemy really struggles to cast spells even at full mana.
