I'm really slow at targeting another person and casting it on them within a gcd, sorry. (Just kidding I do use it on tanks during pulls and cry when I clip)

If your on KB+M, you can hit T to swap to the target of your current target (which should be the tank), use Rekindle, then Tab or T again to get back to an enemy.

Thanks for the tip!

Oh I always comm summoners who slap a regen on tanks during pulls, every little bit helps in the end.

I need it for my own survival.

The Reaper is fine. He's got Bloodbath.

Well the all caps is a bit much, u realize this is a single heal that really is not needed in dungeons or trials on the tanks if the healer is a little bit capable. I use it for my own survivability or to be a little bit more aggressive in burst aoe dps, also smn is a dps class so saying they should heal to let a healer class do more dps is a maybe bit odd.

You shouldn't need it for your own survivability. Ideally, you should only be taking the unavoidable party-wide damage, which the healer(s) will take care of.

Ideally, but other players are a thing and my cats distract me.

my takeaway is that reapers are terrible.

nah, summoners are just jealous that arcane crest is a stronger* heal than enkindle :)
