That is weird. Usually I find tiers 1 to 3 mobs much easier than act 10 (as long as resists are good after the 2nd kitava curse).
Unless they drastically change the rewards, I don't see myself playing this league too long. I will wait until I try the league mechanic in maps before my final judgment.
So far, I haven't seen a good (or half decent) corrupt drop from scourge or created a corrupt item that was better than the gear I was wearing.
Still in acts with not a lot of playtime yet, mostly I'm playing with my son in my lap watching cartoons on the 2nd monitor so I take it slow or afk in my hideout.
I bulked up my res a bit which helped getting through T1-3 maps thus far. Still a little short on both lightning and cold, but they're at like 60%+ so not bad.
The one thing I don't like about my build all that much is after placing the totems, the first "whacks" from the ancestral warlords take a while to start up. It's just a "slow" skill it seems.
And maybe it's just bad luck on my end, but I've been getting crap for currency drops. I struggle to scrape together a couple of chaos.
As far as Scourge is concerned, the only use of it is to pop into nightmare for a few extra mobs. I just have not found any krangled item (or seen anyone brag about any online) that are worth it.
