My name is Reegar and I've got one nice little tip for anyone who wishes to pick up a revenant. It's more of a high level thing, not something à la buzzfeed to get you started. Please note : this applies only to PvE.
So you want to play a revenant? Excellent choice. You may have heard about the legend system and how utilities and buildcraft works (or more to the point does NOT work) for a revenant. You may have also heard about some intensive debate on reddit and elsewhere over energy and how it is supposedly terrible and should be changed. This debate come from people who are used to the other classes and their limitations. Revenant is truly unique among the other classes because of its energy system.
The revenant is the only class in GW2 that uses a form of mana.
When you play a revenant, cooldowns are not a big concern except for a few weapon skills. What will limit you is the energy.
Basically when you play a revenant, instead of wondering "How can I tailor my build to overcome a specific situation ?", you should instead wonder "How can I tailor the use of my skills so that I can put the 100 energy points available to good use in 10 seconds?" Plan the use of your energy in advance. It's though to do especially when you are not completely familiar with the class. However, once you learn what legend does what, this is how you will get better.
Apply this principle and you will see a real improvement of your gameplay in any PvE situation.
There are many other tips I could give to a newbie revenant. However there are already plenty of guides out there that do just that. Instead I wanted to lay down this key principle I believe too few people understand.
