Need advice from fellow Bards

[Jnjeff]

Hi, I've been playing a bard from the first day of FFXIV. I love playing a range class. Ok, enough of the crap and get to the main point.
I am slowly progressing through coil now, and is currently at T4. I'm wondering if I'm doing anything wrong because I do not want to bring the whole group down just because i sucked.

Here's my macro for all the skills
/ac "Haymaker" <t>
/ac "Internal Release" <me>
/ac "Misery's End" <t>
/ac "Bloodletter" <t>
/ac "Heavy Shot" <t>

/ac "Haymaker" <t>
/ac "Internal Release" <me>
/ac "Misery's End" <t>
/ac "Bloodletter" <t>
/ac "Straight Shot" <t>

/ac "Haymaker" <t>
/ac "Internal Release" <me>
/ac "Misery's End" <t>
/ac "Bloodletter" <t>
/ac "Venomous Bite" <t>

/ac "Haymaker" <t>
/ac "Internal Release" <me>
/ac "Misery's End" <t>
/ac "Bloodletter" <t>
/ac "Wind Bite" <t>

/ac "Hawk's Eye" <me>
/ac "Raging Strikes" <me>
/ac "Blood for Blood" <me>
/ac "Barrage" <me>
/ac "Quelling Strikes" <me>

I spam all buffs before starting my attacks which I read some where, saying that, we should activate 2 buffs, GCD skill, follow by another 2 buffs, and then GCD skill again to get the best out of it.

I noticed that i need some buffs up and some not to at specify phase/time, therefore I will be doing minor adjustments here and there to be able to deal the maximum dps.
Is there anything I should change to improve myself? P.S. I spam/mash buttons rather than waiting for 2.5sec GCD
