People often post gameplay from modded realm difficulties and discuss builds they use there. There was discussion about what difficulty should be a template for balance purposes and there is a very important reason for that. Right now we have pretty good balance between weapons/classes and there are some stronger and some weaker but Cataclysm feels hard for a random group of people. Now lets increase difficulty and you don’t even need a modded realm for that, just use twich mode and deeds on Cataclysm and the game becomes much harder. We now see a much wider gap between classes because damage now becomes paramount and if you don’t take meta classes/weapons you become a liability for the team. The second issue of increasing difficulty is “bullet sponge” effect. I played many games that are guilty of it (Warframe, Division, Bethesda games).
What I am trying to say is that veterans should not give advice on bases of moded realm difficulty. The game is not balanced for it and in my opinion the game should be balanced for the highest difficulty available (Cataclysm should be free). I know that there are people that always chase higher difficulty (me included to a degree) but if we do it without care for balance and enjoyment of the game itself it will become stale. Do you really want people only to play BW, Shade and WHC because they are capable of insane damage on DWON3.?
When I am creating a build the first priority is that I will enjoy it. There is nothing wrong in playing optimal builds but don’t try to convince other people that something is worthless only because it is less optimal. I like to challenge myself but if I play too long as one class it becomes boring. There is also downside to it, playing too long as one carrier can make you less proficient in other classes. You will use your special ability in wrong situations under pressure (I do it sometimes when playing too long as one carrier). Enemies are also a resource of THP and for example BW can do insane damage but most of it will not give you THP.
