Are certain skills not viable for the end game meaning that they perform poorly to the point that they are not worth pursuing in an end game build? For example, I can understand that RuneMaster and Runic Invocation builds are popular, but what about a skill such as Volcanic Orb? I’m very new to the game, but I come from D2/LoD and D3. A customizable Frost, Fire, or Lightning Orb sounds awesome. However, I don’t want to put 500 hours into a character and build and the skill isn’t viable. So are there skills that aren’t viable? If yes, then is it listed/documented somewhere? I plan to experiment for sure but I figured it would best to ask before I embark.
