There's a difference between low gear and low skill. You aren't going to do as well as someone in epics, but you should still be able to pull off moderate dps for your gear level. Some low gear people I've seen half ass their way through scenarios/dungeons/lfr/ahune expecting the better geared people to carry them. If your pet dies, it's your fault. Don't complain, just revive your pet and keep pushing on. You're going to deal with intolerant people every now and then, just don't give them a valid excuse to act that way.
