Yeah was about to say, he has a video with a bunch more details. He mentions the Guardian ascendency is getting reworked, apparently to a more combat oriented paladin-like ascendency to go with the new skills. I guess they'll kill the "stand around near people and pick up loot only" support spec shit and instead work on an active support using skills to buff other people like the new lightning aura shit.
He also seems to imply there will be a reinforced focus on minions supporting within the ascendency and the new items to go with dom blow rework. Might end up making my first templar since beta if that's the case. He shows a weapon too crafted with the new shit, a 1H sword with 90%+ minion damage, a 5% damage aura and some proc on hit. The interesting part for me is the fact the 90-100% minion damage weapon mod isn't gone after incursion ends(although they might still add incursion to the game we'll see). The fact you can craft it is even better because you can put it on a fast dagger instead of a slow ass scepter, also meaning I can use whirling blades instead of this stupid shield charge shit.
Overall, pretty excited about this league, although I feel this might turn out as a miss for people who like to grind xp only, as I doubt it'll be time efficient at all to do the delving garbage, but it seems something nice to do after you're done leveling and just want to play the game on that char still. And it looked like unlike other leagues, you can kinda "skip" it, as long as you collect the things on the maps, and then just spend say an hour or two just delving with the ressources you got. It might be capped and force you to delve regularily though, we'll see. And the whole ladder ranking thing seems like it'd be a good way to add some side endgame activity for people in the base game later on.
