We can probably do without the whole Hit Totem -> Danaeus -> Tentacle into totem again -> Instant death thing. The gambit actually just outright kills a specific target (assuming the Wytch has an artifact totem) in team fights. I don't think a radical change is required, but something like a 5 second totem cooldown would do it, since Danaeus drops the target after four seconds. This change would preserve the original intent of totem, but make instakills with it impossible. A more extreme solution would be to make totems work like Ranger Wedge. You set it once, it hits, it has to be reset again.
EDIT: I also think changing this aspect of totems falls more into the realm of hotfix than classleads, considering it definitely seems like an oversight rather than a design decision, @Garryn.
I realize I'm in the minority here, but I'd love some sort of Imperian Twitter (since the IRE one doesn't seem to get much use) that announces stuff like events starting, gem hunts, et cetera. I enjoy playing Imperian when stuff is going on, but when it's just AFK hoping for something to happen, my interest rapidly diminishes.
