So, it went live without much trouble, played some last night and today, about 8 hrs total, up to act5 with my templar.
New skills are a blast to play early on, not sure how much lategame viable but we'll see. Storm burst feels like a fun to use lightning tendrils, has nice range and the channel isn't too much of an issue as a second or two is enough to clear most packs. Divine Ire on the other hand is amazing, the clear is reasonable with a single stage of less than a second charging clears most things and multiple stages chunking bosses in a very satisfying manner. The gameplay isn't as dynamic as most of the clear speed meta monsters out there but that isn't much of an issue for me.
League itself is somewhat confusing to explain and to get into, but once you play around a bit with it, it becomes fairly intuitive for the most part, with a few problematic spots from time to time. The short of it is, maps before maps, every zone you can talk to cavas and do a quick run trough a fragment to activate the spots, if you activate even one you get to keep the shard as a puzzle piece of sorts (up to 10, which is kinda low imo). You don't need to pick up shit as it drops out at the end kinda like incursions and clearing things isn't that important anyways, especially early on when you're missing damage, by mid story it's fairly easy to activate all the nodes and clear most of the map before it collapses on you. You then take these puzzle pieces and arrange them in the nexus to create further chains that you can run for the loot they have, or, more importantly to get to randomly spawning nodes on the board that have extra loot kinda like Delve nodes do. It's about as quick or as slow as you want it to for the most part since pieces once set have several charges before they turn into the race against the collapse runs (and even then, you usually have enough time to clear some packs before it dies on you).
Overall, fairly enjoyable so far, we'll see how it keeps my interest once betrayal bullshit gets introduced in act9 and the various masters start vying for my time come maps.
