TL;DR-- It is not a small advantage, and it is not just for elitists and top-tier raiders.
I ran some quick numbers to show why party buffs are way more effective than you may think. Please keep two things in mind:
- If you do not attempt high-level content, this can only help you! This is to help those of us who really love WHM and would prefer to play it in raids without knowing we are making life harder on our group.
- The below numbers are for PERSONAL DPS.
This means whatever effect you see from the buffs is being magnified several times over because actual DPS classes are being affected.
- WHM Potencies
- Stone IV--250; 100 PPS
- Aero 3--50+40/3s over 24 s (370 over 24s for 1 GCD); 15.41 PPS
- Aero 2--50+50/3s over 18s (350 over 18s for 1 GCD); 19.4 PPS
- Assize--400 every 45s; 8.9 PPS
- 17.5 GCDs every 180s to keep dots up; -24.3 PPS
- Total WHM PPS--119.41
- SCH Potencies
- Shadow Flare--50/3s over 15s; 4.16 PPS
- Miasma--20+35/3s for 24s; 12.5 PPS
- Bio--35/3s for 30s; 11.7 PPS
- Broil--230; 92 PPS
- Energy Drain--150; 3.3 PPS (if no clipping)
- 13.5 GCDs every 180s for DoT maintenance; -17.25 PPS
- Total SCH PPS--106.41
- AST Potencies
- Malefic 3- 220; 88 PPS
- Combust--50/3s over 30s; 16.7 PPS
- Lord of Crowns-300 (occasional)--1 per 180s?; 1.6 PPS
- Earthly Star--200 every 60s; 3.3 PPS
- 6 GCDs per 180s for DoT maintenance; -7.3 PPS
- Total AST PPS--102.3 PPS
WHM's are killing ASTs and SCHs...right? Let's look at the 75th percentile and confirm WHM's dominance:
Wait...what!?
AST vs WHM: WHM has 16.7% more potency per second than AST, but AST beats WHM by 5.7%. This is a swing of 22.4%. Buffs are one cause.
SCH vs WHM: WHM has 12.2% more PPS than SCH, but SCH still edges WHM out by 5% on personal DPS. This is a 17.2% swing. How!? Again, buffs.
I've heard a lot of people say the buffs only matter if you're in the top 1% and chasing a gold parse. This is not true. If you have ever enraged on a boss or struggled to meet a DPS check, you know every little bit matters. Having an AST or SCH in your party is not a tiny boost--it is huge.
Here is a log I ran through xivrdps, which calculates the damage gained from buffs, and breaks it down by ability. I chose it at random, it is a non-meta comp, and none of the participants parsed orange.
Numbers do not lie. The healers will never be balanced until WHM has a buff.
WHM needs a buff if it is to compete. It is that simple.
