- Best Job to give Arrow to is BLM, hands down. In the absence of a BLM then I'd go: BRD > MNK/NIN > WAR. Could include SMN in there if the player is using Ruin IIIs outside of Dreadwyrm Trance (which they should, but not all players do).

- Only cards you'll want to give to yourself is Spear (before using CDs like LA and Lightspeed) and Ewer, otherwise burn them on Royal Road.

- I'd say Extended Cards are better, if only because it means you get a use out of Spear (via RR), instead of burning comparatively better cards (Bole and Balance) to get the Enhanced effect. In 8 mans though, Expanded is better than both (unless it's Arrow; an Extended > Enhanced Arrow would be better IMO, assuming you have a BLM).
