Jump enhancing traits would be most welcome if done properly. I would hope they add traits that increase jump damage and TP gain. Then, add powerful merits like DRK's "Desperate Blows", DNC's "Saber Dance" etc. you get the picture.
From the sound of things, it looks like the next category of merits will look something like this:
--------------------------------------------
Group 3 (Max.total ability increases: 10) (Hopefully it would max at 15 instead)
--------------------------------------------
Call Wyvern Recast [20 minutes → 15 Minutes]
Spirit Jump Recast [00:01:30 → 00:01:15]
Soul Jump Recast [00:03:00 → 00:02:30]
Dragon Breaker effect [Enhances effect]
Jump Effect [Increases damage and accuracy by 5%. Applies to all jumps]
--------------------------------------------
Group 4 (Max.total ability increases: 15[!])
--------------------------------------------
Overall Damage Enhancing JA [Job Ability] (Job ability Haste and Attack Buff)
New Powerful Jump [Job Ability] Merits increases damage, accuracy and TP Bonus - Also has a unique jump animation like the Lancer's jumps in Final Fantasy XIV.
Jump enhancing Job Trait [Causes jumps to deal severe damage. Severe damage increases with more merits]
Wyvern enhancing Job Trait [Like "Strafe", No DRG would merit this unless the upgrade is significant.]
A lot of that is hopeful thinking.
Bottom-line: I am all for increased jump damage if the Jumps do get separated. As Ihm posted, it needs to be significant for it to be worthwhile.
