I have not played any FF game. I have played a few MMO:s before and the things that attracted my to FFIV is that it can be played with a gamepad and the atmosphere in the trailers. I only played short time but I have enjoy three things:
*) That you can swich class so fast (only to swiching weapon). This is a tremendous advantage if you like me enjoy that type of variation. That one thing that is done better in this game then in any other game.
**) Crafting are done in better way then the most other MMO I have played.
***) The game is fully adapted to gamepad so I can play in a relaxed way
I can see the good thing about specialization as long as one character can swich between any classes.
Would be great.
Concerning how to implement specialization. Talent tree is not the only way to go.
There exist alternative ways of making restrictions.
Restriction you can make:
# Great armor penalty.
# weakening some types of abilities.
# Remove access to some type of abilities.
In that way a advanced class would be constituted by 3 things:
- In what parts you get weaker.
- In what parts you get stronger.
- special abilities
For people that like to use the current pick every thing you like Red Mage should be the advanced class. All other classes should have limitations.
Some should be more limed then others.
Ex:
As a Blue Mage you loses the option to use any healing abilities. And gain % on damage.
As a Scholar you loses the option of using any melee or bow/throwing damage abilities. And gain % on magic damage and healing.
As a Black Mage you you loses the option of using any healing abilities and any melee or bow/throwing damage abilities. And gain % on magic damage.
And the bonus should be higher the more you "give upp". So a Black Mage should gain more % on magic damage then a Scholar.
The result would be a bit difference then using the talent tree concept.
The concept I prefer is the one that is use in D&D School Specialization. Basically you choice what to give up and you choice what to gain bonus in.
There two basic advantage over the "School Specialization" concept. It's more flexible and you don't lose the people that likes to play more the jack-of-all-trades.
The more narrow advance classes like White Mage or Black Mage easy fits into the "talent tree concept". But classes that can use both melee and all Magic ("Red Mage") or melee and all magic except healing (Blue Mage) don't fit in.
