Not to mention birds will reflect back, Absorb-STR, Absorb-Acc, Stun, Drain II and whatever else u cast on it. Either gimping yourself or an unlucky member of your pt who pulls hate in the process.
I'm sorry, you do way too much casting. In an even decent merit pt I have time TOPS to fire of one spell per battle. If your brd is even an average puller then there is always a bird at camp and simply not enough time to cast all that junk. You cast all that and by the time you engage the mob it'll already be at below 50% life lol.
Don't waste mp on drain(s) thats what healers are for. Don't bother with Spikes either, if you pull hate that bad that your constantly needing Spikes sub /ninja. I do use Stun and Weaponbash however when I pull hate because there virtually instacast and will buy me 5-10 secs for the mob to die and not be such an mp leech.
Absorb-Spells are meh. 2-3 secs is still an eternity when the mobs you are fight dies in 15 secs and to be honest you will parse better not using them versus the added benefit it gives to a weaponskill. As mentioned 21 STR is not lol 200-400 dmg more.
