Spellsurge is a group ehant. Don't worry about it unless you have multle people getting it in a group. It's something like 11.5 or so mp5.
1.) Unless you have 2-3 others in the same raid group every week
with spellsurge, 81 healing is more worth it. 2.) In yourase, the lurker breastplate is an upgrade, you need therit more than the healing. I'd tually evenonsider using Xi'ri's gift over the P until you get more stuff withrit on it. 3.) The time you wasteasting a rank 4 + the tivation of the Dould easily get your tank killed. I don't rommend downranking just for the libram buff to anyone. They severely nerfed theoefients of downranking so your R4 heal will do next to nothing. However if you're dead set on it, you need to have the equ before the spellast.. something like: #showtoolt Holy Light(Rank 4) equ Libram of Mending cast Holy Light(Rank 4) However, at the end of the spell you would be using your mending libram and not your nagrand one. 4.) It depends on the fight as to whether youan FoL spam. Youertainlyan do it through all of kara, first 3hannelers of Mag, and oe all thehannelers are dead. Some fights in S (ie. Tidewalker) will take more healing, but I don't think you're to that point yet.
1. Regarding spellsurge, it may be worth getting another Essee Fusser off the AH - they are quiteheap - and having one ehant on eh. See whh you prefer. I tried it in a 5-man aouple of days ago, 4asters in the group and it worked well. Sure it was boosting mp5 for me but it kept the tank (prot pally) and others energized as well. If you're going for the S2 me, that doesn't have any mp5 whereas the Essee Fusser does, so you
might feel the benefit of having it. 2. On thehest pies, I haven't worked out how mh 42 spellrit rating would give bk in mana. You might want to take that intoonsideration as well as the +heal. 3. Youan'thange a trinket midway through a fight so you'd either have to do this before the start of the eounter or keep the trinket on all the time. Librams may be different, I don't know about those.
