Well this is my 5th league and I still see announcements that a person did for the first time and say "what is that all about."
The games super but the first character is like a pancake, bad, you'll likely finish the quest line and have to remake to do any end game content.
If you're good at button order etc you can make a harder character. If you're a button masher like myself I suggest righteous fire juggernaut to start. Tanky and decent damage.
As for a guide. I'm not the guy but I can help out with some things.
I dont use a mic and I feel this holds me back. I dont like ready patch notes. I watch the odd video but usual say the hell with this half way through.
But the game is fantastic. It really is!
