Revolution has been live since a few weeks ago. I haven't been keeping up with the exact changes since then due to exams though.
So revolution stuff...

Fiona damage multipliers. HS Counter does more than Amaranth, which I may have mentioned at some point. So HS Counter spam master race.
Lann stuff I'm not able to analyze well enough, so I'm not going to bother. Have some Spear talk though.

There's some talk about both weapon types in there. Just know both Lanns got buffed, significantly even.
And Cestus is apparently around Sword Lann DPS now, for what it's worth.
Also S2E2 Extra

Quick version is that each spell now is either Fire, Ice, or Lightning (like a certain other game that has a section on this site cough cough), and they're positioned accordingly. You also seem to be able to "store" a spell for use later, and you can store up to 3 spells.
Blind Arrow has been changed to lightning and updated to look the part. Left is fire, right is lightning, down is ice.
They're going to need to seriously change the cooldowns though, if they haven't already.
S2E2 Extra trailer.

S2E2 extra weapons (for some classes) and armor look pretty superior to the other 80 sets though. I've already spent enough time digging up data though, so I'm being lazy at this point. The armor is called Noblesse though, if you want to look it up yourself. I think all 80 weapons and stuff got buffed though, like Fiona's Peacock/Heremon longswords both got Att buffs, Hammers got a stupidly minor Bal buff, and so on.
Oh and by the way, we're getting a Kai revamp.

Probably the best way to do it as Kai is so broken as is. Before anyone starts complaining that these are just buffs, Kai is only broken due to glitching right now giving him insane DPS and SP gain, meaning spamming EEA off cooldown is completely viable. If they actually do fix all the glitches, he'll need these changes to stay competitive.
