I'm probably going to catch a bit of flack for this but here goes:
Ya I probably haven't played since 6.?.? whatever. Came back before the last patch take a lvl 70 healing sorc to Drommund Kaas and start doing heriocs, get to the one in the temple, 4 gold guards and the boss. Have companion on dmg, tough fights killing the 4 gold adds , then get to boss dude. Notice two lvl 50+ players standing close but shrug shoulders and send companion.
the Adds respawn be4 boss gets to 1/2 health needless to say I get hammered by the adds and then the half health boss that kills companion.. Don't mind a tough fight but that a bit over the top that a lvl 70 companion and healing player cant kill a level iirc 15 boss.
Just my opinion on the subject
