Numbers are still being adjusted on Beta and the PTR, so I've included updated info on what you'll need prior to the PVP system changes for both Honor 5 and new info on Honor 400. Keep in mind that these are estimates and not exact numbers. Things could also change at any point between now and the pre-expansion 8.0 patch release. (The revamp to the PVP system is coming with the pre-expansion 8.0 Patch, so there's not much time left to earn Prestige/Honor prior to the updates.)
---------------------------------------
With the changes to PVP coming in BFA, there are still lingering questions that I have about it all. Will there be PVP-PVE options, such as Tower WQs, in the expansion? How quick/slow and easy/hard will it be to reach the necessary rank(s) for the companions? What will the Prestige Rank to Honor Rank conversion look like? Luckily the latter question was answered!
A Google Doc spreadsheet (by Vjaera-Proudmoore) was posted in the Bnet Pet Battle forum, and it basically answers what Prestige Rank(s) you'll need to reach Honor Rank 5 in BFA.
There's also an addon (ZigiPrestige found on Wowinterface) that you can use that will automatically calculate it for you, but I wanted to use the spreadsheet to calculate different scenarios.
If you only care about collecting the PVP companions (and don't mind skipping the other PVP rewards), and have already reached Prestige 1 on a character, you will only need to aim for Honor Rank 5 in BFA. This is because Blizzard has essentially switched the pet rewards around, offering up the current reward for Prestige 7 as the initial PVP pet reward in the expansion. DISCLAIMER: This could change at any point before release - be aware that nothing is guaranteed.
Under the current reward system:
Wyrmtongue pets (Prestige 1)
Dutiful companions (Prestige 7)
Under the BFA reward system:
Dutiful companions (Rank 5)
Wyrmtongue pets (Honor 20)
If you reached Prestige 1 during Legion, you've collected what will be the higher reward already. Don't beat yourself up grinding super hard to earn more Prestige Ranks now. But should you stop completely? Probably not.
Based on the spreadsheet's calculations, here's what you'll need prior to BFA to reach Honor 5 in in the expansion. NOTE: Numbers are probably not exact, so expect some necessary adjustments come launch.
To reach roughly Honor 5, you need the following prior to Patch 8.0:
- 1 toon @ Prestige 5, Honor 1+
- 2 to 3 toons @ Prestige 2, Honor 2+ (each)
- 4 toons @ Prestige 2 (each)
- 9 toons @ Prestige 1, Honor 2+ (each)
- 10 toons @ Prestige 1 (each)
UPDATED June 21 (new calculations)
- 1 toon @ Prestige 2
- 2 toons @ Prestige 1
For roughly Honor 400:
- 1 toon @ Prestige ~80
- 2 toons @ Prestige ~40
- 3 toons @ Prestige ~26, Honor ~45 (each)
- 4 toons @ Prestige ~20, Honor ~15 (each)
- 5 toons @ Prestige ~16, Honor ~20 (each)
- 10 toons @ Prestige ~8, Honor ~22 (each)
- 15 toons @ Prestige ~5, Honor ~40 (each)
Feel free to input your own characters' numbers into the spreadsheet to determine your Honor Rank in BFA. You'll need to copy it to your personal Google Docs account so that you can edit it; instructions can be found on the spreadsheet.
Should you keep grinding Prestige now? Personally, I think so, yes. But go at whatever pace feels comfortable for you. At the very least, I highly recommend earning Prestige 1 right now, during Legion. That way come BFA you'll only have to worry about reaching the new lowest milestone (Honor Rank 5).
Again, all of this could change. Values could change, conversion rates could change, the order of pets rewarded could change. Even additional companion rewards could be added. Take this information as just a guideline and not an absolute. We'll have to wait and see when BFA releases what the final outcome will be.
Overall though, this change should be beneficial for most pet collectors. Crossing my fingers that it sticks and everything follows through as previewed.
