I think CH is very good and pick it almost every time. 2v2 when the enemy has a gen ill get it and 3v3 when they have a gen usually too - sooner or later they will also get priests in. Maybe in the 3v3 u can get it later on but I think its worth it Also in 2v2 when ur laning vs another gen its very strong for pushing and lane holding.

However I wouldnt consider myself an experienced sed player.

^That pretty much was my doctrine until recently, too.

However, I've found empirically that enemy monks are either dead or out of range in so many situations (with allied Rook, TB, Occ, QoT, to name a few prominent cases), while you, as Sedna, will naturally outheal enemy generals by a huge margin anyway. Since you are not a farming powerhouse by any means (fastish dynamic Sed I play now is having a much easier time in this respect than a pure support static Sed, but still...), every level counts. Basically, you don't have any points to spare until level 15 or so, and I just don't think CH is ultimately worth it, unless it's a counter to another Sed with CH,

Also, in my opinion, monks' healing is only realistically useful over long periods of time, while laning semi-passively. I've seen it change the outcome of an occasional early-game skirmish, but that happens only very early and, indeed, very occasionally.

She has a lot of useful skills and to me their priority is higher, unless enemies always walk as three generals group and all got different levels of healers. 

Pretty much this, though I'm strongly opposed to NR on Sedna in 3v3. It's not bad, of course, but you absolutely need BoS, 2 helms, Unbreakables and Hauberk.

I dont get it - which other skill is more useful to a sedna in 3v3s than counter healing??????
