Just you.. I had a non SR run last night without a bard and we ended it in 13 minutes without any of the standard giant pulls... I wasn't even aware until I checked the time remaining... In terms of taking hits, I was definitely being hit for less (Warrior) and I could still LoS the crap out of the slime boss' fire attack. The tonberry was just as easily ignored as I ran through him and LoS'ed him around the corner. You may have experienced a train effect... player A aggroed berry and runs.. then b and c follow.. tonberry aggro swaps to b and then to c, followed by d... resetting the chase timer and any successful LoS you had initial performed... It happens.. it's frustrating.. it might even make you want to take out your frustrations IRL... but the occurrence was very much possible pre-patch.
