Much like your motherbox trinket concept *COUGH* DEVS *COUGH*, I'd support this. Why not? it's a feat which already exists, shouldn't be too challenging to implement. Likewise, obtaining it shouldn't be too challenging but challenging enough that it takes a bit of effort to get. I'd support it.
Every feat in this game need to be obtainable, with minimal effort and zero communication, on the very first run! *giggle*
NO... LPvE is for day one players in terms of difficulty. This is supposed to be for everyone as an entry level group experience. YES... To go the opposite of my original response, not every feat needs to be simple and obtainable right away. So go for it. Just don't ***** when trying for this in a PUG group
LOL! You know that's is gonna happen regardless. If this feat does go live, someone somewhere is bound to fail and destroy the image they have in their head that they are god's gift to gaming. Then a new player will show up out of nowhere on the forums and preach in thread after thread about the evils of lpve and why it needs to stop and be deleted from this game.
I wouldn't mind it as an extra feat but doing it the EO way and closing tunnels isn't really any different, both in terms of rewards and time you spend in the instance.
