I would also have to vouch for Sakura too.

Nothing sucks worse than to out-level your weapons and then find yourself unable to hurt a fly around Lv30-40 or so because you can't hit anything, because your weapons are 10+ levels worth of skill out of date. Sakura really helps you keep up with your combat skills and it just seems silly to only allow you to buy him/her/it during one month out of every year.

I would also have to agree with Shantotto II and Kupofried... and yeah, Moogle too. Refresh is make-or-break especially at lower levels.

Amchuchu... I've mixed feelings about. I have seen how awesome they are at later levels, but early levels... I think Trion is better to be honest.

But while we're talking about this... given how they set the DPS bar with Shantotto II .... why not buff a lot of the available DPS trusts so that they are closer to her? I'm not saying to make them all as awesome as she is, but yet... a lot of DPS trusts aren't even worth calling out whatsoever. They don't even do 25% of her damage, even at lower levels. Couldn't we at least buff them to 50-75% of her performance? Especially the ones you gotta quest storylines to get?

I mean, Tenzen and Semih Lafihna are rather powerful in the 30-80 range, but once Semih learns that AoE WS of hers, she's useless (because she'll get you killed or put you in seriously dangerous situations needlessly). Same reason why I don't use Valaineral unless I absolutely must (mules who don't have access to Trion).
