I have tried quite a few builds such as blackbeltman's latest RoJ based build on reddit, but this build kind of seemed like it didn't do enough healing and was micro/pulling orientated. I also tried discord way which was fine but then somewhere I read the more mesmers the better so I bought the mercenary hero packs and tried a 5 mesmer build. This worked quite well but didn't feel fully optimised so in the end I have sort of made my own mish-mash build taking bars from other builds and mixing them into one. Seen as I have no idea what I'm actually doing even after reading countless threads it is probably terrible so any advise/criticism would be appreciated.
