Once you start dropping mechanics you start removing the enhanced mechanics that make and define a raid. Not every raid encounter will use those enhanced mechanics but simply removing the extra tanks and healers necessitates the removal of mechanics that require extra tanks and healers to deal with. You also can't even design around the possibility of hybrid classes, or role switches ot dual specs because of the nature of party formation and class roles.
With your examples, you point out situations where you think dual tank mechanics could work. Thing is...even if you were right, you still can't design around two tanks here. An arms warrior in Defensive Stance lacks the toolkit a tank would have and that limits what the encounter can throw not just at him but also the main tank. It also requires changes into how those echanics scale up into 10s. Single parties also mean no split encounters because only one group can be healed. It limits the encounter because only one tank or one healer will be available.
And so on. You end up not adjusting the fight for lower numbers, but potentially redesigning it from the ground up and still ending up with a fight that can't have all the encounter mechanics multiple parties allows for.
You can have a multi tank encounter with 2 tanks or 5. You cannot have one with a single tank
The games moved away from such gimmick fights. And they are gimmicks unrelated to raid size. If gimmick fights were wanted, it wouldn't be that difficult to put them into the encounter in some way.But what about mages and warlocks tanking stuff off like in tbc.
Yes. It means they have to do less work to get a 10 man group formed, or with more 10s available they don't wait as long to raid.10 package better has more incentives or incentives that 25s do not have.
The raids themselves have no incentives....beyond those minor ones given to 25s, that is. Anyone who wants to do 25s can do so; all they need do is form a group. But that is not Blizzards responsibility and Blizzard are under no obligation to force people to raid that format.
Its easy to tell someone to say no. Less easy to do. You want to be helpful. You don't want to be kicked. You don't want to be the one to hold your guild back. Recommend all the blogs you want, but the fact that people will - for whatever reason, be it good or bad - feel an obligation to raid if the option was there and do so will remain and Blizzard recognising this, recognising the fact this pressure exists, and recognising the multiple sources that cause it is a good thing.take it as possibility to grow up
Not giving end game players more to do was not, but thats what Blizzard is hoping to correct.
