News Flash: TP Gain isn't all that meleeing is about. Especially as a Samurai, the damage on the road to 100%(sans meditate assist) is most likely more than what you'll get out of weaponskilling, even with THF sub. Unless you're busting balls and doing 2000+ damage skills every time you weaponskill, which is highly doubtful. Or using Soboro, which from an efficiency view, I'm not entirely fond of seeing at 75.
Thats actually pretty true for every job now that I think about it, unless you're gimping your melee damage or a THF. Now, don't take that as THFs = gimp damage, it's just how the job works that I'm pointing out. The majority, or atleast more than half, will be from weaponskills.
Maximizing Damage without hurting TP Gain, and vice versa, is how to do it correctly. If you aren't, you fail. Play a mage job.
I know I don't depend on my weaponskills as a Monk to be the greater of the scale, because the "best" one peaks at 1400 on neutral enemies, where as on the climb to use it, I'm doing more than twice the minimal Asuran damage, and a good bit more than your average.
Speaking of Soboro, I'm sure that kills the effect of Bushido cape even further. Since I'm sure Zanshin, like Double Attack, cannot kick in when the weapon multihits on its own.
