I have maybe five hours a week I get to play a game now. Reviews and the scores are actually a very good tool for me. Had I waited on Destiny I might have seen that it maybe wasn't the best use of my five hours a week.
Do power struggles, but before you engage in them get the Intel on the captain you're trying to kill. Lower Level captains have vulnerabilities that can take them out in one hit.
Let's say there's a captain doing a trial by ordeal, and he's vulnerable to stealth kills. Just climb above him while he's fighting and drop on his head for an instant victory. No need to fight 20 orcs. Plus the runes are key. Equip a bunch of runes that give health regeneration based on your play style.
I had the fourth tier of upgrades unlocked this way before I even got to the second map.
Once you get chain shadow strike and two executions per combo streak, no crowd of orcs will ever be a problem again.
The Thor we know is going back to his old axe and is no longer worthy of the hammer. That Thor will be in the avengers comics still. They aren't literally turning him into a girl, that's what Loki is for.
