A few thoughts from a casual player.
These builds are awesome and I appreciative them. As someone said, being thrown off the platform, knocked down, or a variety of other effects is what makes it hard to contribute better DPS, especially when you do not do the content very often. Videos can take you so far.
However, what these builds do is to let me have full attention on my surroundings and look at what the bad guy are doing and react better to it, rather than dividing my attention on the bar to execute the dps rotation and be kicked in the kitten while not looking. More time on target pays off.
One last thing, there are a few post complaining about the people who would complain against elitists, yet there are none in this thread. Feels like unnecessary pre-emptive complaining about complaining...
Anyhow, thanks to the people trying to help, it does for my wife and I.
