When danger rears its ugly head, the smart player is supposed to run from a loosing battle and avoid repair bills. At lower levels particularly, I've found this hard to do, even as a heavy armour wearing Templar "tank" with an instant cast heal on my hotbar. I was told that's just my fault, i'm too squishy, or that I must have waited too long to run etc. so just put it down to being a bad player.
Well, yesterday I was passing through the Ouze in Malabel Tor, saw a player running with less than half health, so I beeline and fire off - honor the dead IV to heal for 345 health.. and as he staggers away with a slow debuff, his health drops rapidly below half again so I cast again, then again, and again, then pot, and cast again, then regen / power return from target being below 50% / warlock set bonus enables me to cast another 3 times. Meanwhile I agro two of his pursuers with ransack from my stamina bar. They finally stop chasing him, but without my aid he'd have died four times over. Looked like a light armour class but he wasn't underlevelled.
Even more surprising, I survived as well. I know the guilt that comes from letting another player die, and i'm supposed to be a support class anyway, so these days I don't even think about it... anyone on low health, run towards them and start spamming your heals and taunts.... almost all of my own deaths have resulted from this after leaving the starter zone (and also from jumping off cliffs that were just a little bit too high).
