Im reading some of the old posts about AA's and most of us seem to agree on one thing, WIS line is shitty. It's taken me a while to find the right mix of points here and there, but I think I've got something you all may want to consider. Remember this may only benefit high-end players with VP set gear or some nice SoH stuff even.
Str line, why I dont use it. The fast casting is nice, but honestly with a bard I hardly tell the difference ( maybe the first ten minutes after spec'ing out of str). Haste. I prefer high delays so I can nail 2 CA's or spells between auto attacks. I really dont need the hate gain with Traks shield or when using a 2 hander.
Agi line, Why I am using it. 4-4-8 Standard deal here, group instances, avatars and SoH trah (4-6 encounters at and time in soh).
Sta line, 4-4-5-2 I can live with 64 melee crit (anything over 50 is good), I few points in HP no DA
Wis line , 4-4-8-6-2 Standard points here, but I'll tell you why I like it. Battle leadership, we have no increase to range, with this group buff, we are afforded the ability to increase our offense just like guardians; all this stuff only benfits us and our group(I think it is leet). Fearless morale: if you have guildies who break down parses and study the little details they will all tell you how much they love this buff dps and healers alike.
Int 4-4-6 The all important spell crit!
With this spec, I tank avatars when needed, I off tank adds when needed and do lots of amazzing shit in instances (like that matters) average VP parses are in the 3k+ range with an occasional 4k, while SoH trash can see @ 5k. And just think fear immunity on Byzola pwns!!!
Give it a try for a week or 2 see how it goes, but try to keep your spell crits above 60 and melee crits above 50(sorry non-raiders) I've been using this same spec for about 6 weeks, my group loves it and it has worked out well for my role with my guild (offtank/dps).
