Just watched Tali do a level 8 run. You can go watch the vod on twitch.
Heres my observations:
He constantly chain pulled.
His bar never really breached the cut off line (eye balling it, around 67%).
He didnt fully explore. But he did clear most of the adds, pots and chained souls.
He died 4 times.
On average, i'd put his bar progress at an average of 45-50%.
His final score was zero gems. This isnt a "LOL noob!" point.
If you'd have asked me, based on the fact he genuinely chain pulled, genuinely cleared most of the content and genuinely pushed, i'd have thought (even with the deaths pulling him back), he'd have been given a couple of gems.
I know we dont know any of the answers by the way, but it has my rogue pretty concerned. I like Torghast in general. I even liked the pre nerfed torghast (that period between the healer/tank nerf (~dec 12th) and the full scale nerf of torghast 3 days later (dec 15th) was pretty awesome). But my playstyle is controlled. I like looking about a bit, taking it in, sapping, making careful and controlled pulls at the right moment - you know... rogues).
But dude was chain pulling. He cleared most of the content. But that bar degradation was brutal.
Toward the end he was genuinely pointing out that perhaps the push push aspect of that bar did change up his gameplay at least (even though he acknowledged that wasnt everyones cup of tea).
Perhaps it was the deaths that cost him severely? But then, it kinda suggests that if you die, you need to restart if you require 4 gems to move forward (5 at 9 and above according to preach). But here's my concern:
That talent tree. It has a talent in it that slows the degradation of the bar. Perhaps its slower naturally at lower tiers and at 8 theres a cut off to the 'new content' (ive only seen preach and tali run it so far). But the dude is heroic geared... whats that? 213-225? Level 8 is like rated around 190 to 200? He played the game as you'd assume it was intended (constantly doing stuff, and clearing). And got zero stars?
I think theres gonna be a riot if this goes live?
ETA: It could really just be a tuning issue. Perhaps 9-12 has had more work on it, whilst 1-8 is basically just the 9-12 system crowbarred on to it. But my worry is that its deliberately like 8.3 cloak. And you've gotta spend several weeks (or months if youre kinda slow) failing whilst leveling those talents before you can seriously step into the actual content of the patch.
