For most avg or slightly better setups fire bomblet performs about the same and bombcore; esp on birds.
I'll use my setup for an example (which isn't stellar):
SKILL 292 = 282 acc
DEX 81 = 60 acc
EQ = 43 acc Total
= 385 acc (410 with aggressor)
Since bird acc caps at 407, anything beyond this is going to get 2/5th value (or less if you merited aggressor)
Finding the value of att/acc on birds: http://ffxi.allakhazam.com/db/jobs.html?fjob=16;mid=1233872604201847924;num=19;page=1
At 86% acc , 1 acc will bump you up 0.58 for 40% of the time = 0.232% damage increase
At 500 att (pre-zerk,chaos roll), 1 att = 0.25%
In total that bomblet= -0.108%
Ok, now you can say you'll be WS about 1.39% more often also.
WS usually comprises 50% of my damage (use your own number if you like),
so 1.39% x 0.5 = +0.695% for bomblet
In total thats +0.587% for bomblet if you have so-so gear and no merits in aggressor, and hasso is off
On higher lvl mobs or thf mobs, fire bomblet starts to shine. Edited, May 19th 2009 2:49pm by doctorugh
