So, regarding Arrow, I only really throw it on someone if I'm sure their TP can take it, so during a small pull, because I really don't have to have to use a Spire on someones TP in a boss fight (especially during raids) when I could've just burnt it. Now, the weird thing is as an AST, I always feel like I shouldn't be using the cards on myself because that's bad and I'm the benevolent buffer healer who reads the fortunes of others and yackity yack *~*. If you don't want to shuffle the Arrow, if you don't want to save it, use it on yourself. Get some Gravity casts in (if you like to DPS), get some faster heals, because who doesn't like faster heals. I...can't speak on the topic of who likes what cards because it really depends on the player.

(NOTE: For those of you who DON'T want a card when it's on you, right click the buff, it'll leave.)
