So I was looking yesterday, and noticed that wowwiki has finally got around to doing some basic boomkin builds that should "get you started" on the pvp front. I'm not really particularly happy with either one of them, though I recognise the need to spec partially into the resto tree to get Omen of Clarity at least, and not go 71 points into balance like I'm currently doing (hey, I like to explore my tree fully). Anyway:
Firstly, the more "serious" pvp build, I like this one less than the other but it has its benefits. I really dislike that this tree tosses both insect swarm, the most mana-efficient dot in the game, and eclipse which I find to be a dps boost. Begin controversy arguing now. I agree with the elimination of starfall, I have that currently and I can count on 0 hands the number of times that I've cast it and not had it get me into exponentially more trouble with the huge range on it. I understand you could put a major glyph into it but I'm already packing the SF & Wrath ones, with the third already slotted to MF after I calculated it would give me a 300-point damage boost (lose 600 from the initial, gain 900 in the dot part). I could toss the wrath glyph I suppose but it's not that worthwhile a talent to me. I'm eh on the elimination of IFF and BoP -- both dropping your chance to hit. I particularly like that IFF when talented gives you an extra 3% crit chance on the target, and it brings you to a 99% hit chance which is pretty damned good. I could probably spare BoP with the hit dagger from the Kirin Tor, at least till I pick up some Arena weapons which probably won't have any hit rating on them. Gale Winds I think is not a particularly useful talent, the added cyclone range is nice but I don't think it's going to be that useful in arena where you close gaps too quickly for any range to really be important.
Second build, allegedly a mixmash if you need more pve viability, I like more. I like this stuff we're getting out of the resto tree, I hadn't realised they added boomkin benefits to some of those talents so it's good to spec into both furor and master shapeshifter. Intensity's a must, obviously, so I would keep this resto side of the tree how it is. Many of the same complaints apply to this build though at least they kept insect swarm. Dreamstate I'm not sure is that important, I don't have OOM issues in Arenas or BGs, deaths are too quick, and you already have Intensity so...
I think I'm going to try this one when I hit 80. Yes I did throw some stuff into Dreamstate after all, but only b/c I had nowhere else to put the last couple talents (same rationale on Owlkin frenzy). Keep my eclipse and the hit chance at 100% (I guess you never know when that extra 1% might be important...).
I wish I knew more about Nature's Splendor -- it increases the length of your periodic spells...does it also increase the damage/healing so that you have the same amount per tick? Or is it the same amount just spread over a longer time, ie, you get less per tick? Nobody seems to have any definitive comments on it one way or the other.
