What could DRK have learned from FFXI?

[LichKaiser]

This is FF14 not FF11. Game is different, HOW you play is different, itemization is different, gamplay is different. Compare 2 class (dark knight) from 2 different games just coz they have the same name is the most stupid idea ever saw, pls stop this threads.
Im loosing brain cells reading.

PS. take "ispiration from" is not "must make it the same" or "similar". Dark Knight is a class way older of FF11 and it worked as both tank and dps, BUT in a JRPG contest. THIS is is a MMO, need to specialize in 1 way, you cant do both. SE choose the tank since the HEAVY armor theme suit more into tank into FF14 structure (dont say Dragoon can use heavy armor, coz his own "iconic" JUMP was based on elude enemy attacks and deal double damage in old FF, that suit more as a damage class then tank in a MMO structure like ff14 + DRG have own unique gear sets different from others).
During DRK making game was like FULL of DPS, no needed of more, Queue was insane long for any DPS, probably that counted to incentivize tank over dps + to make new mechanics and content they made an anti magic tank, and DRK was perfect for that role.

Nowhere the OP suggested that DRK shouldn't be a tank, only that FFXI DRK iteration had some interesting skills/spell that could be added to XIV's DRK to make it a more unique tank.

Hmmm, you can't really use "Jump" as a reason to why DRG shouldn't be made a tank when sacrificing HP to do damage is a concept that you would definitely don't want to see on a tank (In its basic iteration, at least)
