RG's game development career was great during his first 20 years and been crap the last 20 years. People blame EA for Ultima IX, ncsoft's for Tabula Rasa but given the way Shroud of the Avatar is turning out I find that a lot of the blame should fall on RG's lap as well.
His part on other ncsoft games was that his company was supporting the western versions of ncsoft games.
After healing in tera it felt next to impossible going back to tab-target healing. Healing felt far more interactive when you had to target people instead of just mousing over icons and hitting abilities.
