Are there going to be real choices in the spells you use other than making a choice between an aoe skill? We hope that if there are that the skills will add a bit of variety to the look and feel of the fights. Seeing our char do a 4 hit combo with a sword and then our 2 other abilities look and feel so similar that it seems dull. Maybe we feel that the melee dps classes are too similar. Maybe some cool or class defining highly unique abilities that do something other than the basic x dmg, stun, heal.
In addition, we focus on how to feel for a char meaningful or unique. As the class(tera gold) will be only one weapontype, each year in appearance and performance should be a great weaps diversity. The development is looking for more action and less number-crunching, but if only the aesthetics had a great amount of options, then players can connect with the very unique look and feel of their character. Special properties of weapons with either enchants or rare abilities tied tot he weapons innately could help.
We are just thinking of the fun factor of the game. Action games are all about getting in the fight and mixing up all of your abilities and, usually, weapons to take down the tgts. MMORPG's reward you with tons of gearing options, promises of new spells/talents as you level in Tera, and immersion into your "unique" character and their world.
