It's no secret that 1.0 had a lot of things wrong with it and had to be scrapped in favor of our re-worked (yet still enjoyable) adventure in Eorzea. One of the things that 1.0 was known for were more complex stats such as the following which belonged to the original incarnation of DRG's relic:
Gae Bolg
Damage 164
Delay 3.9
DPS 42.05
Piercing 100%
Accuracy+30
Critical Hit Rating+30
Critical Hit Attack Power+100
Store TP+30
Increases Jump damage
The stuff highlighted in red are examples of what 1.0 had to offer. The bold stats are something that would most likely not work with the current system (despite the possibility that things can always change with each expansion).
These days you would normally find a class/job's associated stat along with the appropriate amount of Vitality and anywhere from 2-3 other stats. But what if additional stats could be added onto particular pieces of gear at a later date?
eg.
Wyrmtooth
LNC DRG
Level 60, Item level 145
DPS: 60, Auto Attack: 56.11, Delay 2.81
Strength + 63
Vitality + 74
Determination + 41
Critical Hit Damage + 2%
Conserve TP + 3%
Critical Hit Damage + simply increases the amount of damage dealt with critical auto-attacks and weapon skill damage. Conserve TP occasionally allows the TP cost of a weapon skill to be used while consuming 10 less TP so hopefully nothing too game-breaking.
Aside from the above example, what stats do you think could eventually see a return or be safely introduced without bending the rules too much should the rules themselves be altered drastically?
