So from what I've been reading there is both a lot of good and a lot of bad in the new AA enhancements.
In particular I'm really interested in the imbues, and slayer arrows.
So far, I do not like the new slayer arrow. I can understand some of the thought behind it, being that maybe AA would be a bit to OP if we could have multiple imbues going. So some balancing is appropriate. But I think the Devs are going about it the wrong way in the current version.
My suggestion is as follows;
Make Slayer arrows an imbue, exactly the same as on live, but allow us to use other imbues and effects at the same time. Now to balance this, when running Slayer arrows, and you activate another stance/imbue, the damage from slayer arrows either A. On vorpal you deal 250 Damage instead of 500.(half damage on on a roll of 20) or B. Slayer arrows add a flat +12 damage per arrow. (IIRK current slayers average out to an extra 25 damage per arrow, so again, half damage.)
Basically, you're only losing a small portion of your max DPS potential, and you gain some situational versatility. Obviously this would need to be tweaked, and actually tested. But it seems much better than having another damn clickable attack.
On my current split, I already am almost constantly using all of Trip, Sunder, 4 Ki attacks, Shadow fade, Manyshot, 10K Stars, Pin, Otto's, Adrenaline, Epic Moment, Gears swaps, and dealing with short buff durations from scrolls/low level arti spells. It's just entirely to much already, and to add even more to that... My hot bars couldn't handle it, let alone my brain.
Hopefully this makes sense. I'm half asleep already and heading to bed now.. lol
