There is a work around, 3 choices what i did for my trooper
Either if you have a Charge ability's bring a friend send him inside, duel him and then charge in
Or
Bring a Sage friend with you and have them force pull you in the door
Or
Bring a tank friend duel them and have them pull you inside
(this works for all datacrons like this except the one on Corellia Presence i believe it was i have all datacron but that one, Including the +10 to all)
