For those wondering if it is possible to obtain both of these axes at the same time I'm currently rocking the Richardet's +2 in my main hand and a Richardet's in my off hand. I really love using this setup in Abyssea with the RR & VV Atmas. Even with the low dmg on these axes you can still do 120-150+ dmg per critical hit. The rate of these axes going off 2-4 and 2-3 times happens quite a bit. It can be dangerous though at times since you can easily out dmg your pet but snarl comes in handy for that. ^^
I also have 2x Guichard's +2 w/ STR&Attack that I rarely use unless I feel like doing big rampage dmg in a pt. Hoping to get my EVA axes done once the servers come back online for some better nm solo'ing.
