2. MP re-generation - I actually think the current MP management is very nice and works well... why fix something that is not broken?
Currently only a few classes actually have a way to restore their MP without visiting an aetheryte. That to me is broken, at least to some extent, since it forces players to take skills like Siphon MP just to recover in the field. With no 'Rest' command as there was in FFXI some classes are left behind in terms of MP regen and that's bad when you consider that even melee classes now use MP.
A few things stick in my mind with this letter.
1) They're working their socks off getting most of the things in that we asked for (yay!)
2) They're making it even harder to level DoH classes. (boo!)
3) Potential auto-attack system (yay!)
4) Potential XP penalty on death (boo!)
I'll address those in turn. Firstly, DoH. I love playing as a crafter because it's a break away from the usual grind. That being said, you only really get the chance to level quickly on local levequests, since you'll require materials for anything else. Recipes are vastly increased in complexity over Final Fantasy XI, making them harder to obtain materials for. Not only do I need to be an accomplished weaver, but also an accomplished leatherworker and an accomplished goldsmith as well for various items. All this just to craft a single tunic. Purchasing the aforementioned items gets expensive, so crafting your own materials is not only more ideal, it's practically necessary if you want to level at any speed. Reducing the gains on crafting seems like a backwards step, and I really hope it's balanced out with recipe changes if they decide to give it the go ahead.
Next up a possible XP penalty on death. I'll be the first to admit I hated FFXI's death penalty. Not only did it slap you in the face with a cruel lengthy weakness effect, making you statistically no stronger than an amoeba, but it also beat you over the head with a nasty 10% experience loss causing potential level-downs in large scale fights or bosses. Theres a real danger that the same thing will find its way into FFXIV as they're concerned with people blood-warping back to their last Aetheryte, and with good reason. It's hard to know how to deal with this without some kind of SP or XP penalty yet I really dread seeing that in the game.
Overall its good news but I still have growing concerns over what action might be taken to address those two.
