I'm fairly disappointed in half-elf. Does it cap out at +2d6 SA from the rogue dilly? it looks like it does, but just getting through that costs so much, it hardly seems worth it. They really didn't need to cost 2/enhancement, but then again, we'd still be saddled with AP invested requirements. So I'm currently just picking up a rank or two of Elven Accuracy, 1 stat boost, and 1 healing amp. Not a great use of my race.
I think I've got most of the goodies out of DWS all the way up and to rank 3 on the bottom, a few of the staples out of AA including force arrows, acid arrows, conjure arrows, paralyzers, the temp SP on-hit, Inferno Shot III (at worst it's a short-cooldown +2[W] attack), and the 3rd core rank, W&S Mastery III in arti, and enough Ninja to get to Fade. I don't recall what feats I have...whether I feel I can drop any to get to OC.
I've been running Enlightenment and Haste Boost. Does Dance work with bows now? This is the first I'm hearing about it. Have you used Leg Shot at all? It doesn't have the +[W] that Pin Down does, but I might be inclined to just used that. It's not all that often you have monsters for whom 50% movement speed doesn't cut it, and it has a much faster cooldown.Now that A Dance with Flowers works with Zen Archery, I'm going to LR from Druid to Artificer. Heal scrolls net 396 each for 4 AP, which lets me drop Rejuv for Dance. Full UMD also allows me to incorporate Tenser's Transformation before a Furyshot. I haven't decided what I'm going to replace Empower Heal Spell with yet.
Definitely some things to consider here.
