With the introduction of the iLVL95 Allagan Weapons, PLD and WAR have a distinct difference in their stats such as STR, VIT, and Accuracy.

PLD

Allagan Sword

Previous:
STR 22
VIT 25
ACC 18
Parry 26

Current:
STR 24
VIT 28
ACC 19
Parry 28

+ Allagan Round Shield (which is still i90 based on the database provided on lodestone)
STR 9
VIT 10
ACC 7
Parry 11

these bring the totals to

Previous: w/ Allagan Round Shield i90
STR 31
VIT 35
ACC 25
Parry 37

Current: w/ Allagan Round Shield i90
STR 33
VIT 38
ACC 26
Parry 39

Vs Allagan Battleaxe

Previous
STR31 (match)
VIT35 (match)
DTR18 (N/A)
ACC37 (If this is compared to the Parry stat, then this went up at the same rate)

Current:
STR 34 (not a match)
VIT 39 (not a match)
DTR 19 (N/A)
ACC 39 (If this is compared to the Parry stat, then this went up at the same rate)

Conclusion: If you don't want to raise the Allagan Round Shield to item level 95, then could you compensate by providing the excess stats to the Allagan Blade itself, effectively making it :
STR 25
VIT 29
ACC 20
Parry 28
