After reading all the responses, I find it funny that we are discussing "builds" in a game like FFXIV, where anything different from the standard is frowned upon and not viable at all.

Coming from Ragnarok Online, I got used to the FFXIV system but I really miss all the possibilities you could create with RO class system. A Paladin, for example, had at least 8 types of builds (full support, "caster", full speed, tank, sacrifice, shield build, hybrid duelist and a damage reflect build). RO is a 2002 game. Final Fantasy XIV is a 2012 game and we don't have anything that comes even close to that.

I know the styles are a little different, FFXIV being more instanced and all, but both of them are MMORPGs, and I really wish the devs would learn a thing or two from RO class system and design.
