Dogs depend on which three are up. (lol) You get easy weeks and you get tougher weeks depending on combination.Now I haven't raided 25-mans since TBC, but wouldn't Elegon / Stone Guards / Imperial Vizier all be easier on 25-man? In 10-man, Elegon is a nightmare because your DPS absolutely have to be up to snuff, and nobody can slack on killing their sparks. On 25-man, you have 3 people per spark, so even if one isn't pulling such good burst numbers the other two can save him. Stone Guards you have more tanking options and more DPS to run the tiles. Vizier you can stack Disc priests and have a ton of more healing cooldowns to get through Force and Verve (which I guess is irrelevant now since it's been nerfed to hell)
In 25man Elegon is a nightmare too. It's quite tightly tuned if you go in in ID 1-2.
Vizier is that the boss with the latency check? Those little yellow orbs that spin around? Sorry can't distinguish the bugs by names^^.
Don't know that one didn't give us much trouble, why would it be harder in 10m? You have less people failing to move.
To us only three bosses stand out this tier:
Elegon (He gets fairly easy with gear though)
Will of the Emperor
I'm talking about normals though, no clue how mean 10man HCs are. In T11 they were far meaner than their 25man counterparts.
If you go into 25man early in the expansion you can't have a gimpy tank/healer in 25man as well. Outgearing content fixes a lot of issues though and might be easier to do in 25man due to less mean RNG.If a 10-man raid even has 1 player who isn't up to par in their raid it can drastically impact their progression
