After taking month long breaks in between a week of play time for the 4 months I have come to find that a) people are just really bad at their classes or b) they just don't care about how they play.
I have joined some raid groups with people that out gear me which I admit currently would be some one if full heroic DS loot, but even in the past when I was not geared the way I am now I always found away to be competitive and push myself to the limit. After the break I will go into a few steps that can help improve your DPS with getting new gear or needing to have better gear then everyone else.
1) Dont stand in the fire, or the cookies tornadoes, walls of death or anything else that cause a insurmountable amount of damage really quickly. Also in this category and it applies to probably 90% of Dragons in the game don't stand in front of or behind the Dragon
